I tried all of the last kernel versions. Oopses, kernel panics or hard system locks happen all of them:
/boot/vmlinuz-2.6.38-13-generic ---> the generic oopsedon me just recently /boot/vmlinuz-2.6.38.8-testing+ ---> one of the old versions thought was not tainted by the bug (built it from ubuntu git) /boot/vmlinuz-3.0.14-030014-generic ---> an old version (as above) rebuilt from kernle.org git /boot/vmlinuz-3.2.7-custom ---> oopsed and crashed /boot/vmlinuz-3.3.0-rc4-custom ---> had no actual oopses or kernel panics dumped to a console, however had few system freezes, as well as very unreliable pm-hibernate and a bug when a wireless stops working all of a sudden I am attaching a new kernel stacktrace generate on 2.6.38-13-generic. I saw a few other one without syslog being able to capture them. I do have a photographs of those actually and can attach them as well if needed. First I started to suspect a hardware problem. Ran th mem86 test for about 20 hours without any errors. Installed mcelog, it doesn't seem to help. However, What I could notice though, that two of the kernel oopses had this line: last sysfs file: /sys/devices/pci0000:00/0000:00:14.4/0000:09:04.0/net/wlan0/statistics/collisions At the same time the release candidate 3.3.0-rc4-custom has a bug when the wireless would stop working in the middle of the session. The only way to turn it back on was to reboot the system and rmodding-modpbbing ath5k did not help. Therefore a possible culprit might be the wireless card and ath5k module. I am not sure if a faulty wireless card can crash a system, so for now I do not rule this out as well. I will try searching the net on this matter as well using the wired connection only. ** Attachment added: "kernel_oops" https://bugs.launchpad.net/bugs/922976/+attachment/2826955/+files/kernel_oops -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/922976 Title: INFO: task Xorg/compiz blocked for more than 120 seconds To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/922976/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
