Thanks for taking the time to look at this issue.

Do you then suggest I try upgrading my BIOS? It's the one providing the
ACPI tables, right? Any clue why I don't see crashes without Xen, with a
64 bits kernel, or with earlier versions of Linux (eg: 3.1 for example)?

This happens with linux-headers-3.2.0-1-686-pae version 3.2.6-1 from
SID. Then I just tried upgrading today to 3.2.7-1, and it seems there's
the exact same issue (I didn't care doing a serial dump, but I can if
you wish).
