... when built with optimize=n debug=y
I get first a line like this one:
(XEN) (file=extable.c, line=76) Pre-exception: ff105b48 -> 00000000
Then xen dies because of a page fault in IRQ context:
[ ... ]
(XEN) CPU0 FATAL TRAP 14 (page fault), ERROR_CODE 0002, IN INTERRUPT CONTEXT.
ff105b48 is _not_ the start address of some instruction, it's
somewhere inbetween:
ff105b45: f0 0f ab 02 lock bts %eax,(%edx)
ff105b49: 19 c0 sbb %eax,%eax
Without "debug=y" xen boots just fine. This is x86_32.
