With both suggested patches by Antti Kantee, the problem went away.
Unfortunately, I can't confirm that it was because of the patches,
as an unpatched kernel now stays up, too.

So, either the offending NFS client went away, or the patch fixed the 
problematic state causing the panics. I've left an unpatched kernel 
running, in case I can reproduce the error state, and at least 
statistically show that the patched kernel fixes the problem whenever it 

That is, until you guys have analytically found the problem in the code
and fixed it there. :) Again, thanks for looking into this with such short 

I'll let you know, if the situation changes, if this PR is still open at
