Darn! It happened to me again, this time with the logs, but I missed the crucial point where it said "BUG: Overflow ... ? ... Kernel ..." Here is what I have written down:
WARNING BUG: (Did not completely see this message, something about kernel overflow) At /build/buildd/linux-3.2.0/kernel/watchdog.c:241 watchdog_overflow_callback+0x9a/0xc0 () Watchdog detected hard lockup on cpu 0 Do you know where these logs are saved? At the moment it looks like some sort of kernel bug and some lockup on the CPU. I had looked up the /build directory but it was nowhere to be found. This seems to be the same problem as me, though slightly different http://lkml.indiana.edu/hypermail/linux/kernel/1107.1/02053.html, also this https://bugzilla.redhat.com/show_bug.cgi?id=822287. This, I beleive is the code in the kernel which triggers this log output which may help you to understand the cause of the error http://lxr.free-electrons.com/source/kernel/watchdog.c#L214. ** Bug watch added: Red Hat Bugzilla #822287 https://bugzilla.redhat.com/show_bug.cgi?id=822287 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1043755 Title: Plymouth screen hangs on shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1043755/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
