[Xen-devel] E5606 with no HVM; Assertion 'i == 1' failed at p2m-ept.c:524

[Mark van Dijk <lists+xen@xxxxxxxxxxxxxx>]

Hi Xen developers and enthousiasts,

Recently I have been having a lot of problems with HVM hosts on a dual
Xeon E5606 box. Problem is that HVM hosts don't work on it at all and
crash the server.

Today I got the logging to work over an IPMI console so then I compiled
a fresh xen-unstable. Apart from the message I posted in the subject
the call trace reads as follows:

(XEN) Xen call trace:
(XEN)    [<ffff82c4801e1be9>] ept_get_entry+0x13a/0x28f
(XEN)    [<ffff82c4801da274>] __get_gfn_type_access+0x175/0x256
(XEN)    [<ffff82c4801b5a55>] hvm_hap_nested_page_fault+0x133/0x422
(XEN)    [<ffff82c4801d3c8e>] vmx_vmexit_handler+0x136b/0x1614

The entire log from boot to crash can be viewed at the following link:

Here's the kernel's config

And although I'm not sure if knowing BIOS settings is useful it doesn't
hurt to share the many settings it has. So I captured them and posted
the images:

I hope you can help me with getting this fixed. It's been a nightmare
despite the lack of sleep :) but then again I also learned much along
the way. I triple checked the consistency of the above posts to make
sure they are all from the same build. The problem has been occuring
for a fairly long time now but I had to make sure there was no issue on
my side. I'm still not sure but I'm also fresh out of ideas, so thanks
up front for your help or suggestions.

As always please CC me when you reply to the list, I am not receiving
xen-devel emails because most are way outside my comfort zone...
