Description Jonathan Abbey 2006-04-07 19:06:07 UTC 
Description of problem:

The X server in Fedora Core 5 (xorg-x11-server-Xorg-1.0.1-9) crashes
periodically, with a traceback seeming to originate in FontFileCompleteXLFD.

I've captured two tracebacks for the crash, which I will include below.

I'm not seeing anything consistent which seems to cause the X server to crash..
I've observed it while working with OpenOffice and while working with Firefox. 
The most recent crash occurred while I was switching between Metacity workspaces.

Again, I don't know that there's any connection.  The crash has happened for me
a half-dozen times at this point, but I've not seen any consistency in when it
happens.

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

xorg-x11-server-Xorg-1.0.1-9

How reproducible:

Unclear.  Just use X.

Steps to Reproduce:
1.
2.
3.
  
Actual results:

Server goes black, all X tasks die, and init restarts X and brings up the Fedora
login screen again.

Expected results:


Additional info:

I've been running on the Xen0 kernel recently, but I can't swear that I haven't
seen this on the standard kernel.

X Crash traceback, the first

This is a crash I had in X yesterday, from start to finish of the X session.

Another X crash, slightly different in the traceback

Today's X crash, including everything from the start to finish of the short,
happy life of the Xorg server on my box.
Comment 3 Mike A. Harris 2006-05-23 12:07:01 UTC 
The first crash is from a SIGSEGV, which appears to be in the fb layer MMX
code.  The second crash is a SIGILL, (illegal instruction), which seems like
an unrelated issue.

Please try to reproduce this without Xen, to determine if it is an issue
being caused by running under Xen.
Comment 4 Jonathan Abbey 2006-05-23 14:09:28 UTC 
I ran on a non-Xen kernel for a couple of weeks without seeing any X crashes,
then ran a bunch of yum updates, and have for the last three days been running
on Xen again without yet seeing an X crash.

I don't know how I'd try to reproduce this, unfortunately.
