Description of problem: Kernel 3.3 (3.3.0-8 and 3.3.0-4) makes my machine hangs once or twice a day. No error/warning in log files, I've enabled the sysrq key, but I did not manage to get more informations, just reboot (sysrq + b). I did not notice any particular behaviour or activity when this happened (it happened while screensaver was running and also while working) Version-Release number of selected component (if applicable): 3.3.0-4 and 3.3.0-8 How reproducible: Once or twice a day during normal usage Steps to Reproduce: 1. Nothing special, just running the box. 2. 3. Actual results: Machine is freezed, no response. Expected results: Running smoothly. Additional info:
Can you try installing and booting the kernel-debug build? Perhaps that will provide a bit more information. Also, when it hangs can you ssh into the machine? If it's responding to sysrq-b, you might have luck getting in via ssh and can then see if there is anything in dmesg or /var/log/messages.
I installed the kernel-debug as requested however I was not able to have it work properly. I booted it 3 times in a row and got 3 lockups, twice before the X display manager appeared (but X was starting) and the last time I managed to authenticate but my X session was not fully started when it hung. I was not able to have the sysrq work at all with this kernel (even the sysrq+b command that was working previously). I'm back to the standard kernel now and will try to ssh to the machine next time it hangs and let you informed. Regards.
I got 2 more freezes since yesterday, I tried to access the box while it was frozen but no luck... Is there anything I can do to get more infos on this issue ? Regards.
I made a few more tests this morning, here are a few things that might be of interest : 1) I get the following message when kernel starts (both 3.2 and 3.3) : sdhci-pci 0000:14:00.1: Invalid iomem size. You may experience problems. 2) When booting debug kernel in single mode it does not seem to freeze, but going from there to level 2 or 3 make the kernel freeze within a few minutes (< 5). So it seems that the issue is not X related. 3) I made a test where I booted to level 2 and left a top command running on a tty, and when the kernel "froze" I noticed that the top command was still running but very very slow, it would update every 3 minutes instead of every 5 seconds. Regards.
Issue still here with kernel version 3.3.1-2
Still happening with kernel 3.3.1-3
Same issue with version 3.3.2-1
I don't know if this is relevant but the issue comes up every ~5h : Apr 23 08:22:02 kernel: [ 0.000000] Linux version 3.3.2-1.fc16.i686.PAE (mockbuild.fedoraproject.org) (gcc version 4.6.3 20120306 (Red Hat 4.6.3-2) (GCC) ) #1 SMP Sat Apr 14 00:50:11 UTC 2012 Apr 23 13:21:19 kernel: [ 0.000000] Linux version 3.3.2-1.fc16.i686.PAE (mockbuild.fedoraproject.org) (gcc version 4.6.3 20120306 (Red Hat 4.6.3-2) (GCC) ) #1 SMP Sat Apr 14 00:50:11 UTC 2012 Apr 23 18:17:32 kernel: [ 0.000000] Linux version 3.3.2-1.fc16.i686.PAE (mockbuild.fedoraproject.org) (gcc version 4.6.3 20120306 (Red Hat 4.6.3-2) (GCC) ) #1 SMP Sat Apr 14 00:50:11 UTC 2012 Apr 24 07:43:31 kernel: [ 0.000000] Linux version 3.3.2-1.fc16.i686.PAE (mockbuild.fedoraproject.org) (gcc version 4.6.3 20120306 (Red Hat 4.6.3-2) (GCC) ) #1 SMP Sat Apr 14 00:50:11 UTC 2012 Apr 24 12:41:50 kernel: [ 0.000000] Linux version 3.3.2-1.fc16.i686.PAE (mockbuild.fedoraproject.org) (gcc version 4.6.3 20120306 (Red Hat 4.6.3-2) (GCC) ) #1 SMP Sat Apr 14 00:50:11 UTC 2012
Issue still present with kernel 3.3.2-6. Is there anything I can do track this very annoying issue ? Regards.
I have two additional workstations that started randomly freezing a few times every day after a yum update. For me the problem started after kernel 3.3.1-5. If I boot from that kernel version I don't get the freezes. When the computers freeze they become totally unresponsive and unreachable through the network. Fedora 16 Intel processors x86_64 architecture Nvidia Quadro 1700 GPU (using kmod-nvidia)
Issue still present for me with kernel version 3.3.4-1
I have done some more homework and I don't think that my issue is related to the kernel but a driver issue present in the kmod-nvidia package. A problem for another forum.
