No direction at all to resolve this?
Previously: Bare metal, Intel i686, 8 GB RAM, very stable.
Currently: Xen 3.0.3/4 guest, AMD x86_64, 10 GB RAM, locks up DAILY.
Needless to say, we can't keep the current platform for long.
Bug opened http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1303

I have xentrace files that look normal to me - just a lot of
__enter_scheduler do_block domain_wake on diffent cpu's over and over.
That correlates with the hardware completely pegged during the lockup
time - 50% to dom0 and 50% to domU.

Maybe it's CentOS 4?
Maybe it's drbd?
Maybe it's the above, combined with high load, and memory usage?
Maybe the answer is right in front of me, but I don't see it, and I'm
frustrated, and my office is frustrated.
