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
