Description Alex Butcher 2002-12-22 15:22:57 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 Galeon/1.2.6 (X11; Linux i686; U;) Gecko/20021202

Description of problem:
I'm running mostly Red Hat 8.0, but with a slightly modified and rebuilt kernel
2.4.20-0.pp.7 from Rawhide (to get the XFree 4.3 DRM stuff) and
XFree86- rebuilt under this kernel from mharris' src.rpm.
I've also seen similar problems with previous 4.2.99 CVS snapshots of XFree.

I'm trying to eliminate various system hangs and application crashes experienced
when running 4.2.0 (as found in the RH8.0 release) and 4.2.1 (from mharris'
RPMs) - more applications run correctly with 4.2.99, but the hang when
exiting/restarting X is new to the 4.2.99 series.

It seems not all GLX apps tickle the bug; glaxium and the Atlantis screensaver
seem to consistently though. glxgears seems not to.

The hang is very hard - the kernel doesn't even respond to ARP queries or the
magic SysRq key afterwards.

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

How reproducible:

Steps to Reproduce:
1. Preview Atlantis screensaver
2. Logout
3. Machine locks hard on X exit or restart (hard to tell!)

Expected Results:  X should have restarted at the display manager login

Comment 7 Mike A. Harris 2002-12-22 20:12:13 UTC
Red Hat does not support user compiled software.  If you compile it yourself,
then please report bugs that occur to the linux kernel mailing list in the
case of the kernel, to the dri-devel mailing list in the case of DRI specific
related problems, or to the XFree86 mailing list in the case
of XFree86.  We simply can't debug and troubleshoot all possible permutations
of a user's personal compilation environment.

Comment 8 Alex Butcher 2002-12-22 23:15:07 UTC
I understand entirely, but I also experienced the same problem with the
pre-compiled RPMs. I figured you might be interested to learn that there may be
problems with equivalent configurations before you released 4.2.3. Oh well.
