I noticed 'ifconfig' hanging on my box, so did a sys-request kill, which
killed off all processes except ones which were hung, so captured the
sys-request 'show tasks' output, showing hung processes and kernel threads.

Filesystem is reiserfs - I'm not on the mailing list, so reply directly to
seek further information!
