Hi all!
I am running SXCE 121 on a dual quad-core X2200M2 (64 bit of course).
During an installation of a NetBSD 5.0.1 PVM domU, the entire machine
crashed with a kernel panic. Here's what I managed to salvage from
the LOM console of the machine:

Xen panic[dom=0xffff8300defb2080/vcpu=0xffff8300dfcdc080]: Xen BUG at mm.c:101
That's an assertion failure in Xen, in this case it unexpectedly finds a
level 3 page table entry with the PSE bit set. I can't immediately say
why this happens, but it's definitely a bug in Xen itself, not in the
Solaris dom0.
I can take this up on the xen-devel list.. if there's an easy way to
reproduce it, that'd be great!
