This looks to be an external unknown NMI (unless you can reproduce on
something other than cpu0).

I would have to know what hardware you have and see the dmesg log after
the resume from hibernate.

You can open a bz and assign it to me.

Just attach the dmesg log, lspci and lspci -t output to the bz.

Though this is most likely a pci device firmware problem.  But I can try
to narrow it down.

Cheers,
Don
