Re: [BUG] double fault for sale ;)

Looks suspiciously like a stack overflow (comparing esp and ebp) - did you perhaps add (for debugging) some large stack
objects somewhere? Unfortunately the code isn't clever enough to provide a stack trace in such a situation... Jan

Hi folks,

I'm busy rewriting the domain builder code a bit, to restruct the code
and make it better usable for other tasks than directly booting a
domain.  While testing these bits I trapped into that one:

(XEN) CPU:    1
(XEN) EIP:    e008:[<ff137512>] get_page_type+0x12/0x63d
(XEN) EFLAGS: 00010296
(XEN) CR3:    00000000
(XEN) eax: 33030001   ebx: ff1c1080   ecx: ff1d4080   edx: ff1d4080
(XEN) esi: 0000001a   edi: ffbf5fac   ebp: ffbf502c   esp: ffbf4f84
(XEN) ds: e010   es: e010   fs: 0000   gs: 0000   ss: e010
(XEN) ************************************
(XEN) CPU1 DOUBLE FAULT -- system shutdown
(XEN) System needs manual reset.
(XEN) ************************************

I think even Domain-0 shouldn't be able to crash xen like this, no?

cheers,

  Gerd
