Hello all,

Sorry to bug the list again, but is anyone running xen on recent Dell 
hardware equipped with the PERC 4e/[SD]i controller? I've been having 
issues with random hangs, and I'm trying to narrow down the list of 
possible causes.

Symptom: moderate io causes my xen-running machine to lock hard. Doing
something like "find /" does it everytime, but I've also had hangs while
booting virtual domains, doing a dd, etc. It's happened in both domain0 
and in other virtual domains. This hang during find does not  occur when 
using a stock Debian (2.4.28) kernel nor a self-compiled  2.6.10 kernel 
(which is my first big clue that it might be a xen-related issue). I've 
consulted with Dell on this, and they  recommended a firmware upgrade, 
but that did nothing for my particular problem.

I'm running 2.6.10 in domain0, using the debian packages provided by
Adam Heath. The driver I'm trying to use is the new megaraid driver, not
the legacy one, which doesn't seem to recognize the raid controller at

My first guess was flakey hardware, but testing with non-xen kernels 
makes me think otherwise. Does anyone have any ideas what I could try
