[Xen-users] Xen 3.0 crashes during boot on dual P3 - With option "nosmp" it works

[Matthias Quade <mail@xxxxxxxxxxxxxxx>]

Hi everyone,

I'm trying to get xen running on my dualmachine. The MoBo is a  MSI 694D
Pro with two Pentium 3 CPUs:

The xen-binaries are from 
deb     http://packages.debianbase.de/sarge/i386/xen3/  ./
because I'm running a Debian/Sarge box.
The dom0-kernel is homemade using the linux-2.6-xen.hg merged-tree.
I've done this way severel times on other machines, runnig into no
problems. 

The problems I'm runnig in is a complete systemhang during boottime. It
happens after the Message

The log above is from a systemstart whith these bootoptions:

title           Xen 3.0 with Debian GNU/Linux, kernel 2.6.12.6-xen0 
root            (hd0,0)
kernel          /xen-3.0.gz dom0_mem=64M noreboot nosmp
module          /xen-linux-2.6.12.6-xen root=/dev/hda3 ro acpi=on

That bootes fine.
But without "nosmp" the kernel hangs after saying "Brought up 2 CPUs"
I've tested all the xen options like "lapic, nolapic, noapic, acpi=off"
but nothing works.

I've searched the archives but didn't find anything suitable.
My .config is attached. 

So please help me, I don't know what to do!

Kind regards,
Matthias Quade
