Hi,

i'm pinging this issue one more time...

as you known there's a problem with interaction of mnt_is_reachable()
and vfs elements (especially with autofs with short 1 sec unmount timeout)
which leads to deadlock on all smp cores during heavy i/o workload.

i've uploaded few screenshots with random oopses from kernel-3.4.0
with the latest vs2.3.3.4 patch: http://pluto.agmk.net/kernel/

could you please investigate this problem?

BR,
Paweł.
