Hi,
I'm having xen dom0 crash during bootup when using the linux 3.1 kernel
however it worked when using the linux 2.6.34 kernel.
I tried using xen-unstable but got the exact same error as with xen
4.1.1.
xen-unstable changeset: 23981:6c583d35d76d
linux kernel 3.1.0
I've included the backtrace below.
let me know if you need any more info.
Peter

So Xen reported that memory ends at 000000061ffff000

But what is weird is that the PFN is 555555..

I get the exact same error here. Reading from your output, it seems we have the
same hardware; I have this problem on a HP ProLiant DL380 G6, too.
After a wild hint from a guy on ##xen to play around with the BIOS settings, I
was able to narrow down the problem to a setting called "MPS Table Mode". It is
set to "Full Table APIC" by default (with which the crash occurs), but when it's
set to "Disabled" Xen boots the kernel just fine.
FWIW, the help text of the setting is: "Multi Processor Specification (MPS)
Table / APIC Setting is used for interrupt routing. Certain unsupported
operating systems may require setting the MPS Table Mode to APIC Disabled."
(BTW, the kernel itself boots fine without Xen. So I'm not sure if this belongs
to the LKML at all.)

Oh nice. What does you /proc/interrupts look like compared to baremetal?

It does not. But CC-ing xen-devel here for further tracking.
