Please attach you X configuration file, and X server logs using the
attachment link below.
Comment 2 Mike A. Harris 2002-01-18 03:20:12 EST
Also..  Please upgrade your kernel and other packages to the latest
official erratum releases.

This is most likely a kernel issue.

Have tested this with the 2.4.9-13smp kernel and issue still exists.
Comment 7 Matt Domsch 2002-02-01 11:27:07 EST
Dean, please try with kernel 2.4.9-21smp.

Word from AMI may help, or not.

The following video modes are NOT supported under Windows 2000, and could be 
related to Linux as well.

It's OK to share with Red Hat. 
Note that this issue arises due to the limitation in memory bandwidth of our 
current ATI Rage XL implementation. Dell is using a 32 bit frame buffer memory 
interface with the Rage XL chip. The stock driver which we have been using was 
written for the 64 bit memory interface.

Comment 9 Mike A. Harris 2002-02-13 14:19:24 EST
From what you describe above, this seems more like a hardware flaw to
me than a software flaw, however if that is the case, about all we can
do is detect this video card, and disable all of the above video modes,
so that the server does not crash.

Could you please see if it continues to occur with the 4.1.0-15 XFree86
erratum release?  If so, please also test the rawhide version of XFree86
and see if that changes anything?
Comment 10 Mike A. Harris 2002-02-13 14:33:39 EST
Also, if the above testing turns out to not solve anything, I will
contact ATI myself directly to discuss the problem, and seek assistance
at finding a solution.

Comment 11 Matt Domsch 2002-02-28 16:48:46 EST
Dean, have you tested this with 2.4.9-21 or the new 2.4.9-31 kernel yet?  
Jaguar's trying to get out of system test and wants to know what's up with 

Mike, any other news from ATI on this?
Comment 12 Mike A. Harris 2002-03-07 15:34:39 EST
SOrry for not responding earlier, I've got an updated driver in now that
might work.  It's been in the last couple releases.  4.2.0-6.41 being

Can you test it out and update the report?

Comment 13 Dean Oliver 2002-03-07 15:59:03 EST
Problem seems to be fixed with new driver!!
Hampton beta 2
Comment 14 Mike A. Harris 2002-03-07 16:39:03 EST
Fantastic.  Again, sorry for the delay notifying you of new packages...
bugzilla is becoming a universe of its own to keep track of.  ;o)

Thanks for testing and responding so quickly.
Comment 15 Matt Domsch 2002-03-07 17:13:05 EST
Are the new packages slated for:
1) Errata release for 7.2
2) Pensacola release
3) Hampton release


Comment 16 Mike A. Harris 2002-03-07 17:33:47 EST
Hampton,however it is possible any erratum released prior to that could also
contain the fix as well.
Comment 17 Mike A. Harris 2002-04-17 14:37:21 EDT
Update:  This bugfix will soon appear in XFree86 4.1.0 erratum packages
for Red Hat Linux 7.1 and 7.2, and also are slated for inclusion in
Pensacola as well.
Comment 18 Mark J. Cox 2003-06-25 11:52:32 EDT
An errata has been issued which should help the problem described in this bug report. 
This report is therefore being closed with a resolution of ERRATA. For more information
on the solution and/or where to find the updated files, please follow the link below. You may reopen 
this bug report if the solution does not work for you.
