  Wow, that seems like a long time ago.  Sorry for not posting an 
update.  Since then I've run 2.4.1[678] with xfs from split patches and 
CVS.  The last was 2.4.18+split patches+an nfs patch that Steve? posted 
to the list.  That resulted in ~35 days uptime before hanging with the 
oops appended below.  I'm now running 2.4.19-pre6aa1 (which includes xfs 
of around Mar 30 timeframe I think) and a patched ips (IBM serveraid) 
driver which does highmem io, and have been up for 10 days.

  Note this is a very busy 8-way 8G campus mail server.  The 2.4 kernel 
and xfs have been steadily improving.  I think I can say now that yes, 
it does all work.  I don't know how soon I'll get to see triple-digit 
uptime but I'm optimistic.

Jim
