Since now I have a test case for the problem, I'll compile 2.6.38.2 and
try to see if recent modifications to MM do help in our situation, or if
something else is causing the kernel hang (maybe nfs3 client, as Matteo
was suggesting?)

Yes, I took a shot at applying the patch by myself but it wouldn't be
anybody's cup of tea. MM has radically changed since 2.6.32

The messages are produced at 60 seconds interval. Sorry for the bad
stack trace in the first posting, I hope the full 1-minute stack trace
in my second posting was enough.
I'll keep you posted with results of my tests, so that anyone else
running in the same problem can follow my steps, in case.
