Transient panic on boot with wily proposed kernel (4.2.0-39)

[Mike Gerow]

Attached picture of panic, although there's not really much there. It kinda looks like init has decided to kill itself.

It's only happened once in the three times I've booted into the new kernel. I haven't had a chance to test it more beyond that.

$ cat /proc/version_signature
Ubuntu 4.2.0-39.46~14.04.1-generic 4.2.8-ckt11

[Mike Gerow (gerow)]

Also relevant, I have installed a few dkms modules that could be causing trouble (including one that is unfortunately closed-source and that I can't share...):

$ dkms status -k 4.2.0-39-generic
bbswitch, 0.7, 4.2.0-39-generic, x86_64: installed
hpuefi, 1.0.3+gg8, 4.2.0-39-generic, x86_64: installed
nvidia-340, 340.96, 4.2.0-39-generic, x86_64: installed

Company policy disables apport, but if there's anything specific I'm happy to provide it.

[Mike Gerow (gerow)]

If none of y'all are seeing anything like this in the proposed kernel I wouldn't be surprised if it has something to do with my setup, so this bug probably shouldn't block the release.

Do you happen to have a way to reproduce the panic? Also, Is it only happening with 4.2 based kernels?

[Mike Gerow (gerow)]

Sadly no, I only saw it happen once and I have no idea what might have caused it. The one and only time I saw it was with the 4.2 kernel, though.

I don't have access to the machine that it happened on anymore, unfortunately, but I'll see if I can reproduce the issue on another machine I have access to.

[Mike Gerow (gerow)]

I haven't seen this happen in a while and I'm beginning to think more and more it actually had something to do with my system and not the kernel. Moving to invalid.
