[Bug 1301439] Re: General Protection fault
I can't test easily against mainline due to some API changes in the kernel that are blocking stable zfs builds. In any case I have tested in against 3.11 and it doesn't appear there. I'll close 'kernel-fixed-upstream' based on the 3.11 test and will open a different ticket if it reoccurs in trusty. ** Tags added: kernel-fixed-upstream ** Changed in: linux (Ubuntu) Status: Incomplete = Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1301439 Title: General Protection fault To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1301439/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

downgrading the kernel (to the precise kernel) seems to eliminate the problem. Can try upgrading to the newest too if that is helpful. root@toma:/usr/src# uname -a Linux toma 3.2.0-60-generic #91-Ubuntu SMP Wed Feb 19 03:54:44 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1301439 Title: General Protection fault To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1301439/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.14 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.

I have tested it against a newer kernel (3.11) from saucy and the bug is fixed there.
