Thread-topic: [Xen-users] Xen failing to boot under Debian Etch. (FATAL TRAP)
I'm not sure if this is helpful or not, but we are running basically the
same setup:
2x Quadcores
16 Gig RAM
Intel S5000PSL (S instead of A) 

It could be that you have an older rev of the hardware that isn't able
to upgrade properly.  Not sure if you've checked it out - but there is a
matrix on Intel's website:

        Running xen on a Debian Etch platform and about every 1 in 10
boots I am getting the following error:
(XEN) ************************************
(XEN) CPU0 FATAL TRAP 6 (invalid opcode), ERROR_CODE 0000, IN INTERRUPT
(XEN) System shutting down -- need manual reset.
(XEN) ************************************

(I have attached a file with the full output also of an OK boot and a
failed one also).

This is a Quad-Core, Dual CPU system currently running with 4Gb of RAM
with a Intel S5000PAL server motherboard. I have tried tweaking around
the APIC options to be bigsmp to no help at all. I am kind of at a loss
right now as to how to progress. I have upgraded the BIOS to the latest
revision to no avail also.

Here are the xen package versions from my system:

If I can help with any further information please let me know. Anyone
any ideas on how to fix this problem?

(I will start running the Intel Platform Test Suite to check its not the
hardware, but I doubt it is since this happens the same on two identical
