Christopher, for the last few months I've been testing a whole range of kernel versions of 2012-2011. The last one was 3.4.0-rc1. The pm-hibernate bug was present in ALL of those. Why to expect a fix in that last one? I don't see a single pm commit there. Branches >3.2 break the sound input for me as well. Now I am running "2.6.38-14-generic #58-Ubuntu SMP Tue Mar 27" without a single hibernate. It is as solid as rock. That is why, the bug is in the pm-hibernate module, possibly somewhere in the way the memory is dumped on the disk. I've got across a few such old pm-hibernate regression bugs from the git logs.
The question is to identify the piece of code in pm-hibernate module that causes it. One interesting fact is that in all of the kernel oopses I got there was " last sysfs file: /sys/devices/pci0000:00/0000:00:14.4/0000:09:04.0/net/wlan0/statistics/collisions" At the same time I can see that when I don't suspend machine to disk and it is stable, nm-applet process is constantly leaking memory getting up to 300 megs when I restart it. Perhaps it is not a mere coincidence. -- 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: Kernel Oops - BUG: unable to handle kernel paging request at 850f08bc; EIP is at kmem_cache_alloc+0x50/0x100 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
