[arch-general] Lock at shutdown with some kernels

Hello, I've been using Arch 64 for a year or so, and I remember several times (roughly 5) I have shutdown issues with the latest kernel (at the time). The system is locked at shutdown, I can do nothing but to press the power button to force a power off. I am very sure it is locked --- NumLock doesn't even respond. And it doesn't return to tty as it would otherwise. It came to me again. This time I decided to have linux-lts installed. I'm curious, why is the problem always about shutdown? Is this bug from upstream or Arch patches? I don't have other distros installed by now though. Btw, how does linux-lts differ from linux? I found the -lts one boots very slow for me, got stuck at "Waiting for UDev uevents to be processed" for quite some time, around 30 sec. With linux it's similar, but not so long. I have this issue when I use vga_switcheroo, to switch between Intel graphics and ATI card.

Hi, I've been having the same issue in a dell precision M4300. It started in some point of the kernel 3.1.x release. Since then from time to time the system does not shutdown unless using the power button to force a power off. Any ideas? I can provide more info if I'm instructed about what would be interesting to provide. The computer has arch 32bits for more than 2 years. Hector On 30 March 2012 13:42, XeCycle wrote:

I believe I've heard reports that a BIOS upgrade solves this. I have this issue on a Dell Latitude E5520. I haven't got around to trying the upgrade yet, though. Paul

I will try to update the bios then, Thanks On 30 March 2012 15:10, Paul Gideon Dann wrote:

Perhaps I'm not so lucky. I used to experience some wifi problems, and Lenovo's customer service did an BIOS upgrade. But I'm still having this issue. -- Carl Lei (XeCycle) Department of Physics, Shanghai Jiao Tong University OpenPGP public key: 7795E591 Fingerprint: 1FB6 7F1F D45D F681 C845 27F7 8D71 8EC4 7795 E591

Thanks for the hint, but shouldn't make sense for me. I don't have this piece of hardware, therefore this module isn't likely to get loaded. The problem is I don't know what's happening when it hangs. Otherwise I could have debugged it myself. -- Carl Lei (XeCycle) Department of Physics, Shanghai Jiao Tong University OpenPGP public key: 7795E591 Fingerprint: 1FB6 7F1F D45D F681 C845 27F7 8D71 8EC4 7795 E591

On my Toshiba portege laptop I found that if it hangs at "init 0", that "halt" works and vice versa. Not sure if that helps at all.

New subject: [arch-general] Now looks like display issue (was: Lock at shutdown with some kernels)

Hello, Last night I thought the bug may have come again, so I decided to use another way to shutdown. I think switching to tty1 then login as root and shutdown will tell me what's wrong maybe, so I pressed Ctrl-Alt-F1 --- and the system hangs. So it failed to switch to tty1 and hung, now looks like a display issue. I use latest kernel from [core], have a ATI Mobility Radeon 5650 and Intel Core i5 (1st gen) switchable graphics (MUXed) operated with vgaswitcheroo. I use xf86-video-{ati,intel} along with dependencies from [extra], all up-to-date. Also is xorg. Can you give me some extra hints on debugging? -- Carl Lei (XeCycle) Department of Physics, Shanghai Jiao Tong University OpenPGP public key: 7795E591 Fingerprint: 1FB6 7F1F D45D F681 C845 27F7 8D71 8EC4 7795 E591

Thank you.

A patch is needed, see https://bugs.archlinux.org/task/26847. Comment at end by me. Took me quite some days to figure out this is actually a bug in IPv6. netcfg doesn't expose this kernel bug, bug NetworkManager does. Hope someone can test this patch with linux-lts and networkmanager (preferably -git one since the release has bugs with IPv6), I'm too lazy to do that now. -- Carl Lei (XeCycle) Department of Physics, Shanghai Jiao Tong University OpenPGP public key: 7795E591 Fingerprint: 1FB6 7F1F D45D F681 C845 27F7 8D71 8EC4 7795 E591

Bug can be also activated with heavy process, like building firefox for example.

I deactivated NetworkManager for now, because it made my computer life horrible. -- Frederic Bezies fredbezies@gmail.com
