I received off the list suggestion to try a patch from -CURRENT for
vfs_lookup.c. I think that this patch is already commited to -STABLE,
and so i rebuilt my kernel and world again today, but the problem is
still here.
The machine deadlocked very hard this time, it even stopped responding
to ping requests.
This time i was rsyncing this monstrous imap mailbox (about 8G),
and ran several times "du -sh Maildir" on the target machine,
everything looked ok, and then i decided to run "iostat" and when i
pressed enter the shell freezed.

I will try to setup debugger on the serial console tomorrow to see
if i can get some useful info.
I'm open to suggestions on how to debug this :)

Thanks,

Niki
