I had one kernel crash (11.4 RC1) that might be related to this. It crashed the
next day: I had left the system in suspend to ram mode, but the nfs mount
wasn't removed, I had forgotten, and the server was hibernated to disk and not
restored in advance to the laptop:

See the nfs module listed above?
It did not crash immediately, it froze some minutes later (keyboard caps lock
LED unresponsive -> keyboard frozen), and I had to powercycle the laptop. When
I analyzed the log, after rebooting, I saw the "oops" message.
I have, after this, hibernated the system several times, and this hasn't
happened again. But I haven't mounted the nfs partition either.
I have reported this as:
Bug 673188 - Kernel oops, system freezes soon after.
I will reopen this one temporarily just so that you can consider if this crash
is related or not to the current issue. You decide then if keep open or close.
