Hi list,
I have a problem with a new laptop (reproducable on other machines too) and the
xen hypervisor.
When the hypervisor gets booted with VESA mode 800x600 I see some messages and
then the screen contents is switched into a pattern of vertical colored lines
and never comes back.
In text mode all works well, but later the pattern appears when the X servers
starts.
I disabled VTd in the bios and now all went fine.
I saw this first with SLES11 SP1 but could reproduce it with the xen-unstable
hypervisor.
When I start the linux kernel native on the machine with or without VTd all
is running very well.

(XEN) Xen is relinquishing VGA console.
(XEN) *** Serial input -> DOM0 (type 'CTRL-a' three times to switch input to

(XEN) Freed 184kB init memory.
With staring at the console I could see that the switch to the screen pattern is
around the following messages (but no guarantee):
(XEN) [VT-D]iommu.c:1332: d0:PCI: map bdf = ff:0.0
(XEN) [VT-D]iommu.c:1332: d0:PCI: map bdf = ff:0.1

(XEN) [VT-D]iommu.c:1332: d0:PCI: map bdf = ff:2.3
I would say that this is a problem with the bios tables or with the
hypervisor not handle these right. Always the switching of the gfx card into
graphics mode seems to lead to the problem.
Any help would be very helpful.
Thanks.
Dietmar.
