I saw that 3.11.0-15 included a couple of backported fixes for shm races, including one (8380e1f50d3640498a3fec272ce32199de788a2d) that described my bug nearly exactly. I've been testing this kernel for the last couple of days, and have been unable to reproduce the kernel oops, so I think we can call this bug closed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1249719 Title: Kernel oops - BUG: unable to handle kernel NULL pointer dereference at 0030; IP: [811c07c7] touch_atime+0x17/0x140 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1249719/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The 3.11.5-031105.201311251400_amd64 (6b8fe6d417f93fa628779b1afd9e7717bbcb0572) kernel is bad, I was able to trigger the oops. However, the oops was only triggered after several days of usage, making me uneasy that the cause of the oops might be present in earlier kernels and I simply failed to trigger it. In the meantime until I get a new kernel to test, I'll go back to some previous kernels and test them a bit more to see if I can trigger anything. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1249719 Title: Kernel oops - BUG: unable to handle kernel NULL pointer dereference at 0030; IP: [811c07c7] touch_atime+0x17/0x140 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1249719/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Will do, though the new specified commit (8bacb5ad41da1fde1c05165515c50e2911f16899) is actually before the previous commit (dbb563ec7b143323dd31520ab08c08394bc13381), which usually happens if bad is reported to the bisection, whereas all the results to date have been good. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1249719 Title: Kernel oops - BUG: unable to handle kernel NULL pointer dereference at 0030; IP: [811c07c7] touch_atime+0x17/0x140 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1249719/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I'd like to perform a bisect to figure out what commit caused this regression. We need to identify the earliest kernel where the issue started happening as well as the latest kernel that did not have this issue. Can you test the following kernels and report back? We are looking for the first kernel version that exhibits this bug: v3.11.4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11.4-saucy/ v3.11.5: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11.5-saucy/ v3.11.6: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11.6-saucy/ You don't have to test every kernel, just up until the kernel that first has this bug.
