[Bug 291801] Re: e1000e mutex contention
Even with the original kernel the problem happened only twice and then never again. Let me make a timeline before I get confused (feel free to skip it): 2008-10-31 10:14, I install linux-image-2.6.27-7-generic to 2.6.27-7.15. 2008-10-31 10:28, I reboot into the new kernel 2008-10-31 10:51, I reboot again (with the 'profile' boot option). The boot takes a really long time, then crashes with a kernel panic (blinking capslock led). The panic is not captured in the system log files, and is not visible on screen due to usplash. It's not related to this bug, I think. 2008-10-31 10:53, I reboot again without the 'profile' option. The boot is successful. 2008-10-31 11:17, I suspend. 2008-10-31 14:05, I resume. 2008-10-31 20:04, I suspend. 2008-10-31 20:04, the errors start (5233 repetitions of 'e1000e mutext contention' on this day.

[Bug 291801] Re: e1000e mutex contention
Hi Marius, Would you be willing to confirm if this issue exists with the upstream e1000e driver as well? If so, this is likely something we'll want to try notifying upstream about. You will have to compile the upstream kernel, but this is documented at https://wiki.ubuntu.com/KernelTeam/GitKernelBuild and should be a simple process. In the future we hope to have an upstream kernel package for you to use, but for now we still have to ask to manually build and test. Definitely let us know your results.

[Bug 291801] Re: e1000e mutex contention
Suspending the laptop (a Thinkpad T61) is what triggers this spew of e1000e errors. The laptop sleeps fine, but the errors appear just before suspend and continue after resume. rmmod e1000e stops the error flood, but a subsequent modprobe e1000e hangs burning 100% of one CPU core inside the kernel. The modprobe process can be stopped with SIGQUIT (C-\). -- e1000e mutex contention https://bugs.launchpad.net/bugs/291801 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
