I reverted the patch in 1.3.84 and recompiled but unfortunately it still
stalls. :(

I produced some traces while the transfer stalled, using the
magic-sysrequest-key.

The stack-traces of the afs kernel-threads and of afsd can be viewed at:
  http://leo.kloburg.at/tmp/openafs/

(Filename is kernel-trace1.txt to kernel-trace4.txt.)

I'm not sure if each trace was captured in the right moment but maybe
there is some useful information in there...

Is there any other information I could provide?

Cheers,
