Looking at thhe oops message, this is with a 3ware card, right?
We've had at least one other report of them causing problems on systems
with >4GB enabled (or maybe it was you?)

Yes, I am (or was) using a 3ware controller, since the on board sata
controller is a marvell one, and the native linux drivers seem flaky as
can be. I've only had the 3ware card for about a week, and don't believe I
have written about it. I was going to ask on this list about the MCE,
since I don't know of a better list for asking questions about big opteron

I was the other who reported (via bugzilla, #402) a crash with 3ware. I was told the 3ware driver does not look >4GB safe. I run the same hardware specs using other (non-xen) kernels using PAE and >4GB and have absolutely no troubles though. I am still in a re-testing phase since 3.0.0 was announced. I have yet to put customers on this setup (which is where whatever can happen, will happen).
