While this probably is not helping much to find the issue, I want to add that I was able to get a panic once when kexec'ing into the dump kernel (had to set nomodeset to avoid higher resolution textmode):
PANIC: early exception 0d rip 10:ffffffff8103ee66 error 77b cr2 0 The RIP points to the retq (actually a near ret/opcode c3), the 0d is a #GP (general protection) exception. I am not yet sure what the 77b vector exactly means, but it sounds like the return address on the stack may point someplace wrong. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1022561 Title: Quantal : kexec kernel not triggered when kernel panics To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1022561/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
