Thanks for the additional testing, Olli. The rc1 kernels in comments #10 and #22 should be the same builds. One way to tell would be to boot them and run uname -a, then compare the build stamps.
It sounds like we've concluded the following: v3.10 final: good v3.11 rc1: bad v3.11-rc4: good v3.11-rc5: bad It appears this bug was introduced in 3.11-rc1, but was fixed in rc2 or rc3. Then it was introduced againg, or a similar bug introduced, in rc5. Since we are bisecting between 3.10 and 3.11-rc1 in bug 1218004 , it might be best for us to focus on the bisect between rc4 and rc5 with your bug. The v3.11 final kernel has now been released by Linus. It might be a good idea to test this kernel to confirm it still has this bug, or if it fixes it. It can be downloaded from: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-saucy/ Can you test 3.11 final when you have a chance? If it still has the bug, we can continue with the bisect. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1214931 Title: kernel oops in free_task To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1214931/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
