Can you bisect ?

I looked over the stated range and I do not see a revision that would be
an obvious candidate for the regression. I could think about r345955,
r345980, and r345982/r345983 as something that might be most interesting
to try.

Are there any more details about the issue ?  It is not clear, does the
machine survives the event, i.e. did kernel paniced, what are the console
messages, any more details that you can provide.

Long time ago there was a similarly sound bug where mountd(8) signalled wrong
process, which caused ssh sessions termination.
