[arch-general] Kernel freeze on boot with kernel 3.10.x
Hello everyone, since kernel version >3.9.x (e.g. 3.10.3, 3.10.10) my system freezes during the boot. I was hoping for a fix to appear in later versions of 3.10. but as this was not the case, I am in dire need of help to debug this problem as currently I am not even getting any logs from the crash. Problem: After grub is loaded the system loads the initial ram disk and I am prompted to enter the password for my root partition. After that the system starts normally (systemd messages) and freezes at some point. The last message printed differs a little bit between boots, but it is roughly about "Mounted Config File System". The freeze is apparently a complete crash: I started a systemd rescue console on tty9 (which startup is printed out) but I cannot switch in that console after the freeze (no response on key events). Apparently the logs are not yet written to the harddisk as I can not find any entries on that boot if I startup another kernel. I would be grateful for any pointers on this issue and/or some suggestions how I can at least get a useful log from the crash to open a bug report. I am using the standard arch linux packages (at least where the bootup is involved). My system is using a raid1 with encrypted root partition. And yes, it works flawlessly if I downgrade the linux package to <3.10.x. My hardware configuration (hwinfo output) can be found under: www.ncbecker.de/pc/hwinfo I ran hwinfo with the lts-kernel. Cheers Nils

Even if you can't get a decent log, you might want to consider git-bisect and reporting this upstream.

Dunno what to do with that, I can't even tell if you're not a HP pavillon as in [2]. As I made sure to fully be clear about with my last kernel problem, could you tell us which 3.9.x exactly was the first to break for you? I made absolutely sure it was 3.10.6 which was the first that broke for me and I found the fix in the arch forums [0], I just believe there's quite an importance in knowing this - as it also would shorten down bisecting kernel-git quite a bit. Look, similar issues can be found in [1], [2] and [3] at least. To be very unfair, seriously, you took your time to speak up... cheers! mar77i [0] https://bbs.archlinux.org/viewtopic.php?pid=1319586 [1] https://bbs.archlinux.org/viewtopic.php?pid=1299482 [2] https://bugs.archlinux.org/task/34358 [3] https://bugs.archlinux.org/task/35188

Thanks for your answers! At the time I wrote the email I was too busy to do the kernel bisect and needed a working pc. I did it now. (btw: it was introduced with 3.10.0... did a full bisect...) Turns out the problem was introduced with a patch to the driver of my tv card. This problem is thus "solved" by unplugging my tv card which I rarely used anyways ;) I submitted a bug report and hopefully someone who understands the offending commit can create a fix: https://bugzilla.kernel.org/show_bug.cgi?id=63551 cheers Nils
