[Xen-users] PCI: Not using MMCONFIG, leave system completely hung while booting Xen 3.4.1

Hi Everyone,

I am trying to setup xen3.4.1 FC12(xendom0) on top of FC12 freshly
installed. I am using DQ965GF intel mother board having intel VT-x enabled.
I have installed everything properly, but xen boot gets stuck at this point,


xenbus_probe_init ok
ACPI: bus type pci registered
PCI: MCFG configuration 0: base e0000000 segment 0 buses 0 - 255
PCI: Not using MMCONFIG.


I did few googlings and found few discussion at this point.
 http://lists.xensource.com/archives/html/xen-users/2009-11/msg00537.html
So,  I disabled ''pci=nommconf'' option from grub.conf and
booted xen but
again it stuck at this point,
xenbus_probe_init ok
ACPI: bus type pci registered

This is my grub.conf entry for booting xen,

title Xen 3.4.1 Fedora (Michael Young PVOPS)
        root (hd0,1)
        kernel /xen-3.4.1.gz
        module /vmlinuz-2.6.31.6-1.2.80.xendom0.fc12.i686.PAE ro
root=/dev/mapper/vg_xen-lv_root   pci=nommconf
        module /initrd-2.6.31.6-1.2.80.xendom0.fc12.i686.PAE.img

What is wrong with my system. I am able to run xen with similar
configuration on Lennovo T400 laptop.
I just need any workarround so that I can boot intel board properly. Without
xen, I am able to boot 2.6.31.6 (latest build kernel) without any issue.

[Xen-users] PCI: Not using MMCONFIG, leave system completely hung while booting Xen 3.4.1

Hi,

Please can anyone look into this issue and suggest me  what should I do to
over come with this situation ?  I posted this query 4 days back but I
didn''t get any pointer to proceed further. Will bios update be helpful 
in
this situation?
Any help will be appreciated.

Thanks in advance,

[Xen-users] Re: [Xen-devel] PCI: Not using MMCONFIG, leave system completely hung while booting Xen 3.4.1

1). Get your serial cable hooked up.
> title Xen 3.4.1 Fedora (Michael Young PVOPS)
>         root (hd0,1)
>         kernel /xen-3.4.1.gz
2).  Add ''com1=115200,8n1 sync_console console=com1,vga
guest_loglvl=all loglevel=all''
>         module /vmlinuz-2.6.31.6-1.2.80.xendom0.fc12.i686.PAE ro
> root=/dev/mapper/vg_xen-lv_root   pci=nommconf
3). Take out the ''pci=nommconf'' and add: "debug
loglevel=10 initrd_ignore_loglevel sysrq_always_enable earlyprintk=xen
console=hvc0 initcall_debug"

4). Report back with the whole serial output.
