dmesg after error
Description of problem:
Sporadically, the screen will go black, and then come back with some corruption. Logs indicate that acceleration has been disabled, and things like scrolling on web pages become extremely jerky.
In addition, logging off will cause the screen to go black (GDM does not reload). You are still able to change VTs and reboot the system properly.
Version-Release number of selected component (if applicable):
It varies. Sometimes, you're able to use the computer without glitch for quite some time. Other times, it will happen within minutes of boot.
Steps to Reproduce:
1. Install EL 6.1 on 845-based workstation (I haven't had a chance to try 6.0, so I don't know if the behavior is the same there or not; I can try on another 845-based system if it would help narrow things down)
2. Boot into runlevel 5 with X
3. Watch it go black and corrupt the image during normal use
Corrupted graphics; disabled acceleration.

Xorg.0.log after error
I went ahead and downgraded to xorg-x11-drv-intel-2.11.0-7.el6.i686 to see if that helps. I'll let you know my findings.
So far, it seems there are at least no errors in the logs. However, I haven't been at the machine myself, so I can't say what the experience is like. The main user is someone who probably won't notice as long as things are "working", but I'm assuming it's working well.
It looks like the user's still seeing the occasional issue with the older driver, but the logs look like it's happening a lot less frequently (and might be a slightly different issue).
Since RHEL 6.2 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.
Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.
So I have found what I believe is a workaround for this. I haven't been at the machine since I made these changes, but I don't see any of the errors that I was seeing in the logs, and the system has been up for over 9 days now. While running the 2.11.0 version of the intel driver, I created /etc/modprobe.d/drm.conf with the following:
options drm_kms_helper poll=0
That makes no difference running the 2.14.0 version, as the errors still occur, but that in combination with 2.11.0 seems to work.
I have purchased an AGP card for this system that I plan to install this weekend, so I'm not as concerned with this issue anymore. However, I'll let y'all decide whether you might want to keep this open to track a future fix or not. I can test future updates on similar systems I have at home.
Hi! It's likely that you may not even have this machine anymore but I figured it was worth a try asking anyway, do you know if this issue is still occurring on 6.7?
I'm sorry I've been silent on this issue. I haven't had access to a system with this hardware for several years now, and I doubt it's a valid concern anymore.
I think it's safe to close this bug. Sorry again for being absent from Bugzilla for so long.
