Hello.
I'm facing an annoying bug with linux 4.9-1 kernel on my 6 or 7 years old Toshiba Laptop. When I try to make it boot on with linux 4.9-1 kernel, it freeze right after loading initramfs.
4.8.xx kernel was working flawlessly. My eeePC (nearly 9 years old) and my desktop computer (which is AMD based) are both starting with linux 4.9.
I opened a bug : https://bugs.archlinux.org/task/52246
Here is my lspci. If someone can help me finding what is happening, I'll be very happy :

Does the fallback boot entry work?
Have you tried reinstalling the kernel?
I wish arch would (like other distros) keep 2 or three old kernel versions around because it doesn't take any space to do so and works around boot bugs in new kernels.
If this is a regression you will have to post dmesg. If you don't see errors/warnings, then kernel developers would usually ask to enable debug flags for printing more information during boot.
That said, I have one old machine with a Core2Duo and GM4xx and ever since DRM's atomic modesetting was introduced in 4.2, I can only use 4.1 warning free. Regressions do happen but you had no warnings or errors in 4.8 so yours looks like a different regression.

Care to explain how "doesn't take any space" works? Last time I checked files do take up space. There is an LTS kernel in the repos, which you can have installed exactly for things like this.
There is also the matter of automagic bootloader configuration change to support that, not to mention people that use efistub to boot their system, how do you propose to handle that?

If you don't report the bugs upstream they don't get fixed, if you have reported it and no one got around to take a look at it then fine, otherwise don't be lazy and report those bugs and help get them fixed.

Exactly. I never actually needed it, but I have linux-lts installed and configured in systemd-boot for cases like this. Keeping old kernels around doesn't solve more than this does, *and* opens up more security issues.
I even remember to test that every now and then :)

I did report it and it's been written off as "why do you care about the new warning/stacktrace?". Given that I didn't bother trying to convince the DRM devs of the importance since I don't have a RHEL or SLES support contract I pay for.

The kernel only might not take much space but you have to take into account the initramfs images and kernel modules too. All together it should amount to over 100MiB per kernel.
What other distros do is recommend a 1GB /boot or changing the configuration to reduce the number of older kernels installed[1]. People have complained about small libraries needing to be installed as being wasteful, at a grand total 100MiB+ for each kernel that would start a nice flamewar.
There is also the matter of automagic bootloader configuration change to support that, not to mention people that use efistub to boot their system, how do you propose to handle that?
If you have installed archlinux, it's reasonable to expect that one knows how to configure this.
It is you who said "I wish arch would (like other distros) keep 2 or three old kernel versions around" not me. Other distributions automagically take care of updating the bootloader configuration, as much would be expected of arch.
Some people already have trouble managing to update one kernel properly, imagine the chaos it would be with more than one if manual steps were involved, not to mention old kernels have _known_ security issues and having old stuff around is not the Arch way.
If this is a regression you will have to post dmesg. If you don't see errors/warnings, then kernel developers would usually ask to enable debug flags for printing more information during boot.

Then you've done your part and no one can fault you, if the drm devs don't think it is a problem there isn't much you can do. That said, if the only problem is seeing some spam in the output of dmesg I can understand why they wouldn't give it top priority.

Fair point. My suggestion was of course for the default arch kernel to have at least one alt version there as a fallback and I think one of old LTS branches would make sense, if you don't happen to require 4.10 for AMD Ryzen or have a similar requirement.
Knowing that there's 4.1-lts or 3.18-lts in the boot menu that works good enough to access the system and fix any boot issue with 4.9 is invaluable, if we stop suggesting to people to make small /boot partitions. Unless you're in a constrained environment, it isn't a big deal to allocate 2G for /boot and even 1G would be plenty enough for one stable kernel and a fallback lts kernel as the emergency boot option, plus more.
I have 4 different kernels, all with two initrds in a 256MB /boot partition and still over 100MB free. The biggest initrds are the fallback ones and those are around 20MB.
For one standard arch config kernel: 5MB vimage 8MB initrd 22MB initrd.fallback
35MB * 2 = 70MB.
With a 256 /boot partitition we can have two versions per variant (linux, linux-old, linux-lts, linux-old) and still be good in a constrained /boot.
It's less space needed than I thought.
If this is a regression you will have to post dmesg. If you don't see errors/warnings, then kernel developers would usually ask to enable debug flags for printing more information during boot.
That said, I have one old machine with a Core2Duo and GM4xx and ever since DRM's atomic modesetting was introduced in 4.2, I can only use 4.1 warning free. Regressions do happen but you had no warnings or errors in 4.8 so yours looks like a different regression.
If you don't report the bugs upstream they don't get fixed, if you have reported it and no one got around to take a look at it then fine, otherwise don't be lazy and report those bugs and help get them fixed.
I did report it and it's been written off as "why do you care about the new warning/stacktrace?". Given that I didn't bother trying to convince the DRM devs of the importance since I don't have a RHEL or SLES support contract I pay for.
Then you've done your part and no one can fault you, if the drm devs don't think it is a problem there isn't much you can do. That said, if the only problem is seeing some spam in the output of dmesg I can understand why they wouldn't give it top priority.
Xorg wasn't working properly and seeing stacktraces caused by atomic modesetting regressions and those being brushed off as warnings to ignore, either means their kprintf's are bad or they (Intel) don't have a lab with all the supported GPU. It's one thing to stop supporting a chip in a driver, but if you claim support it's important not to regress. This is why people like RHEL and SLES and I cannot blame them, but I think the better solution is that of a stable ABI, where you limit the security potential just one old driver, which is bad but not as bad as having to use a complete old kernel not just one driver.

Well, we already expect people to take care of orphans themselves, and nobody is suggesting old kernels *must* be kept around forever.
There is also the matter of automagic bootloader configuration change to support that, not to mention people that use efistub to boot their system, how do you propose to handle that?
The blatantly obvious way would be with a dummy kernel package containing a symlink to the vmlinuz/initramfs of the latest versioned package. Old bootloader configurations don't care about how many new and irrelevant files aren't being looked at.
If you want new bootloader entries to be automatically added in grub.cfg then simply use a pacman hook to re-run grub-mkconfig -- I am sure something similar can be easily done for syslinux/EFI. You can also edit the boot cmdline from grub itself...
If you have installed archlinux, it's reasonable to expect that one knows how to configure this.
It is you who said "I wish arch would (like other distros) keep 2 or three old kernel versions around" not me. Other distributions automagically take care of updating the bootloader configuration, as much would be expected of arch.

What problems are people having with updating one kernel? Please elaborate on your vagueness.
As for known security issues and keeping old stuff around, I could care less about offering all kernels in the repos -- I just don't want my old kernel to be uninstalled until I say so.
See http://bugs.archlinux.org/task/16702 for more details, but the basic gist is that versioned kernel installs are a *good* thing, as opposed to being forced to reboot every time your --sysupgrade includes the kernel (which is what *I* would call not-very-Arch-way), and it is intended that we will eventually get versioned kernels, and the fact that we don't have that today is simply because it is low-priority and tpowa hasn't gotten around to it yet.
(I am not entirely sure what the holdup is, though.)

Symlinks won't work, as the filesystem of the ESP is generally FAT32. Trying to automate adding it to bootloaders is also a bad thing, as Arch has no idea how the user has set them up.

Automagic updates? No thank you. Stay away from my configuration files and efi variables.

Forgetting to reboot, which you address below and I have to agree that as things are now they are not optimal. Forgetting to mount /boot and all the "fun" stuff that every once in a while pops up in the forum.

4.8.xx kernel was working flawlessly. My eeePC (nearly 9 years old) and my desktop computer (which is AMD based) are both starting with linux 4.9.
I opened a bug : https://bugs.archlinux.org/task/52246

I wonder if there is any dmesg logged while booting on initramfs... Will try to see anyway.

I wonder which option listed here is the culprit.

As I asked in your bug report, can you identify the processor as well. Here is what I am seeing as of now - one Ivy Bridge laptop does not boot.

FWIW 4.9 does boot on an AMD machine, at least a self-build rt patched 4.9.
