Xorg & xen problems

Xorg & xen problems

[Jerone Young]

Hi all,
	While looking into bugzilla #76. The first thing you notice (if you are
using an IBM thinkpad (w/ati radeon video)) is that when Xstarts it
never fully comes up. I checked the xorg log and while it can see the
video card it just stops!?  Now on my Thinkcenter desktop with i810
integrated graphics it will start X. But when you kill X you just end up
with a blank screen. The machine is not crashed .. but no way to use the
console anymore.
	
	Rolling back to a changeset from June 9th using 2.6.11.11 kernel I have
no problem getting Xorg up and going on my Thinkpad. I think something
has gone wrong when switching to 2.6.12 or some Xen change between
June9th & July 12th is causing this. Any ideas?

That's what I'm currently upto actually...Just takes forever to
recompile every time...hopefully I'll find it quickly.

It would be great if you could do a 'binary chop' between June 9 and
July 12 to try and narrow the changeset down. 

I'm wandering if vm86 mode has been partially broken?

Changeset 6194 fixes broken /dev/mem, which could affect X servers. If 
the repository you were testing with was older than that (it was 
checked in about 6 hours ago) then it's worth retrying with latest...

OK it looks like that fixed it....I must have pulled just before that went in.
