I did some more tests: issue not seen w/ UP kernel (GENERIC) on client.

Other things which didn't help:
 - disable swapcache(8)
 - using UDP for nfs mount

All builds are '-j 4' (or '-j 3'; actually '-j NCPU+2').

I also had a panic while doing 'reboot' on client during a nfs stall:
Fatal trap 12: page fault while in kernel mode
. .
db> trace
. .
(i jotted down more detail, please respond if they are needed)

On most occasions doing 'reboot' during nfs stall just stalled.
