Description Warren Togami 2002-05-01 10:43:53 UTC

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; Q312461; .NET 
CLR 1.0.3705)

Description of problem:
This is the same VA Linux 1000 box mentioned in Skipjack Bug 63284.

Within Red Hat Linux 7.2, sometimes when the X server has been running idle in 
kdm for a week or two, it will crash and use 100% CPU until it is killed 
manually.  It subsequently comes back without problems.

This has occured 4 times within the past few months.  Very difficult to 
reproduce, but it seems consistent after long periods of inactivity at the 
server console.

I have not experienced the Acceleration induced system crashes of XFree86 4.20 
(Bug 63284), but I am testing XFree86 4.10 now with "noaccel" enabled to see if 
this is a related issue in the older version of XFree86.

Version-Release number of selected component (if applicable):
Red Hat Linux 7.2, fully patched
XFree86 4.10

How reproducible:
Sometimes

Steps to Reproduce:
1. Leave VA Linux 1000 box sitting idle in KDM for a week or two.
	
Actual Results:  
X crashes and uses 100% CPU until process is killed.

Expected Results:  
X shouldn't crash and use 100% CPU.

Does this problem occur in Red Hat Linux 7.3?  Recommended disabling
acceleration with Option "noaccel" as well due to another reported bug.

Also recommended, is reporting this problem to the upstream
xpert mailing list, and driver maintainer as I have zero
C&T hardware or specs.

This is believed to be fixed in rawhide XFree86.  Please reopen the
report if you still experience problems with the current rawhide
X.  Be sure to rerun Xconfigurator to get a new config file.
