Description Chris Kloiber 2006-02-20 18:58:32 EST
Description of problem:

Running xorg-x11-server-Xorg-1.0.1-6.1 with nv driver on Geforce 6600 (PCI-e)
from Test3 trees and have experienced a single horizonal line of corrupted
pixels approximately 24 pixels from the top of the screen. You can "erase" the
corruption by moving a screen around over that area, but eventually it will come
back. There are some activities (can't tell which) where you can watch the
corruption occur. indeed this may not really be an X issue, but another
application overriting screen memory. There is nothing unusual logged, and no
problems running X. It seems most noticible right after login, or if you leave
the desktop sitting there a while.

This is what the corruption looks like some of the time.

Are you using Xen?
Comment 5 Mike A. Harris 2006-03-06 20:50:00 EST
Ah yes, from the log:

Current Operating System: Linux borg.ckloiber.com 2.6.15-1.1955_FC5hypervisor #1 
SMP Wed Feb 15 16:02:06 EST 2006 x86_64

This problem happens on Radeon hardware using the "radeon" driver as well, and
is increasingly looking like a xen kernel bug.  It appears as if kernel console
messages get displayed to video memory still.
Comment 6 Chris Kloiber 2006-03-06 21:19:38 EST
I was, yes. And you are right about the radeon driver too. This happens on my
x86_64/radeon m10 laptop as well when Xen is installed (right before the laptop
preforms an emergency thermal shutdown because there's no acpi/cpu scaling in
Xen, but that's another bad bug).

Will you be passing this to the kernel team then?
Comment 7 Mike A. Harris 2006-03-07 00:52:42 EST
Yeah, I guess we can consider this a dupe of bug #182578
