Crashes with large SuperMicro based server.

Hi!

I'm trying to run a NetBSD based Xen server on a 3-year-old server with
a SuperMicro X8DTU/X8DTU-F motherboard with 2x Intel(R) Xeon(R) CPU
E5620 @ 2.40GHz (in total 16 cores), and 24 GB of RAM. It also sports an
Areca RAID board, which isn't recognized, but that's a different
story. It boots both 6.1.5 and 7.0_BETA (GENERIC) nicely (for some value
thereof ...), as long as there's no Xen involved, and I use the on-board
(non-RAID) disk controller.

If I try to put a Xen hypervisor in there, the hypervisor itself seems
to boot nicely, but the following netbsd-XEN3_DOM0 will either crash
with a stacktrace, or just hang and go blank. I've tried both xen41 and
xen45. No cigar.

When using the xen41 hypervisor with the 7.0_BETA dom0 kernel, it
repeats the following message in a burst, then hangs for a few seconds,
then blanks the screen and goes catatonic, with the fans revving up to
max.


fatal page fault in supervisor mode
trap type 6 code 2 rip ffffffff80540792 cs e030 rflags 10246 cr2 0 ilevel 8 rsp
ffffffff81048c30
curlwp 0xffffffff80c3c420 pid 0.1 lowest kstack 0xffffffff810482c0
kernel: page fault trap, code=0


Which are the best ways to debug the situation?

Are there any limitations I should know about (# of cores, max mem)?

Are there any BIOS settings that I need to check? (CPU flags?)

Are there any known compatibility issues with the MB/CPU/MEM?

Are there any combos of hypervisor and kernel that are less or more
likely to work?

Are there BIOS devices that can get in the way and should be
removed/disabled? (USB, COM, IPMI ...)?

Should I look at the PCI bus? (RAID board)?

Are there any settings I need add/remove/change in /boot.cfg? My current
attempt looks like this (all on one line):

menu=Xen:load /netbsd-XEN3_DOM0 console=pc;multiboot /xen.gz
 dom0_mem=512M,max:512M dom0_max_vcpus=1 dom0_vcpus_pin=true
 bootscrub=false

Here's the dmesg from NetBSD 7.0_BETA (GENERIC.201503021830Z) (i.e., no
Xen):
