[Xen-users] Xen 3.0.1 on Debian sarge kernel crash on Dual XEON Machine

[Ralf Schenk <rs@xxxxxxxxxx>]

Hello !

I'm using the latest xen packages from
http://packages.debianbase.de/sarge/amd64/xen3/ on debian sarge
with the provided kernel linux-xen0-2.6_2.6.12+xen3.0.1-0tha6_amd64.deb
(xen-linux-2.6.12.6-xen).

I successfully installed that combo on a Tyan GT20 Server with an
Athlon64 3000+ (Venice), 1GB RAM . Thats running fine, I made some
debootstrapped filebased debian sarge systems with xen-tools - no problem.

Thanks to Ralph Passgang for this nice compilation !

However this was only testing - My real machines are a twin of
Supermicro servers (Equipped with mainboard X6DHR-TG
(http://www.supermicro.com/products/motherboard/Xeon800/E7520/X6DHR-TG.cfm).
2x XEON 3,2 EMT64 with 4 GB RAM and SATA RAID1 (HW-Raid aacraid).
Chipset is Intel 7520 (Lindenhurst).

These machines are normally running sarge (64bit) and kernel
2.6.8-11-em64t-p4-smp for one year without problems.

I installed the same packages, created initrd and so on and tried to
boot the system with Dom0 with xen-linux-2.6.12.6-xen.

XEN loads and starts to boot up the kernel but then the kernel crashes.
I connected a serial console and logged the output (see attachement).

I played around with various xen and kernel parameters like acpi=off,
noirqbalance, nosmp, nousb, noapic, apic=..... with no success.

I thought of an ACPI related problem and updated system bios to latest
bios from January 2006. Nothing helped. If I want to boot to my normal
system after such a crash I've to power the machine off (not reboot !)
and erase the BIOS PCI Tables (ESDT Tables) to get it up and running
again. If I don't do this even the standard kernel crashes while
initalising.

I downloaded latest xenoppix and booted the system off the cd. This
works ! It uses the 2 CPU's (plus the 2 HT CPU's), since it is 32-bit
with no PAE extensions I can only use 3 GB of my physical RAM. Also the
provided knoppixU DomU boots up fine.

After 2 days of rebooting this system I've no more ideas. I can use the
xen console to provide other information if needed.
