I'm having the same issues as Rob on a Dell PE1850 with LSI (53c1030)
rev 08. With Xen 2.0.6 (Kernel 2.6.11), the system immediately freezes
(hard lock-up) upon any intensive I/O (be it rsync, cp, tar, dd).
Using ignorebiostables works, though not having SMP is a bummer.

Are there any other workarounds to this (unstable? kernel patch?)?
There was a post that mentioned something about ServerWorks issue in
the kernel. I'll do more testing. Any help is appreviated.

Thanks!
