current dom0 panic on domu launch

[Sarton O'Brien <bsd-xen%roguewrt.org@localhost>]

Hey all,

Updated a few times in the last couple of days, the most recent being 
yesterday (Wed Sep 30 14:23:55 EST 2009).

A minute or two after launching a domu this is produced:

uvm_fault(0xffffffff80c2dc60, 0x0, 1) -> e
fatal page fault in supervisor mode
trap type 6 code 0 rip ffffffff80564e93 cs e030 rflags 10246 cr2  0 cpl
0 rsp ff

panic: trap

panic: trap

dump to dev 18,1 not possible
panic: wdc_exec_command: polled command not done
Faulted in mid-traceback; aborting...

rebooting...

If more info is required, it's easy to reproduce, let me know what to 
do. If I don't launch a domu, raid parity will calculate and the system 
will appear stable.

I've reverted to:

NetBSD gogeta.internal 5.99.11 NetBSD 5.99.11 (XEN3_DOM0) #1: Tue May  5 
19:23:01 EST 2009  
root%mx0.cre.local@localhost:/usr/obj/sys/arch/amd64/compile/XEN3_DOM0 amd64

Though only because I couldn't find my 5.99.15 backup kernel. Everything 
outside of my own list of known issues with this kernel appears to be 
running fine.
