Description Naoki 2006-09-25 05:18:41 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686 (x86_64); en-GB; rv:1.8.1b2) Gecko/20060821 Firefox/2.0b2

Description of problem:
kernel-xen-2.6.18-1.2689.fc6 boots but X fails.
I get graphical boot ok, I get "Starting firstboot..".   Then it flips to what should be gnome starting up but I only see the cursor for probably half
a second then the screen goes blank and I can't break out of X and need to
cycle the box.

Version-Release number of selected component (if applicable):


How reproducible:
Always


Steps to Reproduce:
1. Boot to kernel-xen
2. Wait for graphical boot to compete.
3. The cursor is displayed for a very short time, less thana second, then nothing.

Actual Results:
Screen goes blank, monitor reports "no signal".  I then need to power cycle the box.

Expected Results:
Gnome start up followed by normal use.

Additional info:
From fedora-devel list :

"I had the same problem. I assumed it was my CPU (Centrino) or my
graphics card (R300)."

Comment 1 Stephen Tweedie 2006-09-25 08:28:39 UTC

Just to check, does the non-xen kernel work OK?

Comment 2 Naoki 2006-09-25 08:47:15 UTC

Sorry Stephen I forgot to add that.  Yes the non-xen kernel works as expected
and is stable. 

I fear this may duplicate a bug I have already opened with similar symptoms :
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=207432

Could this also be related I wonder? :
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=207254

Comment 3 Stephen Tweedie 2006-09-25 10:50:54 UTC

I've no idea if #207432 is related.  There is a change_page_attr() bug being
worked on, but there's no information in this report to give us any idea if it's
the same problem.

Is there any extra information you can provide?  /var/log/xorg* logs, kernel
messages from /var/log/messages etc. after X dies?  As long as it's only X, not
the whole kernel, dying, then the log messages should all persist until reboot.
 (You may want to reboot into runlevel 3 to avoid the new boot overwriting the X
logs.)

Thanks!

Comment 4 Naoki 2006-09-25 11:07:54 UTC

About the best I can offer right now this from 'messages' :

Comment 5 Stephen Tweedie 2006-09-25 12:05:20 UTC

Right, I'll close it as a dup.
