[FIXED] Random Sig'11 in XF864 with kernel > 2.2.x

[FIXED] Random Sig'11 in XF864 with kernel > 2.2.x

[Jeffrey Ingber]

The problem mentioned in the following threads:

http://www.uwsg.indiana.edu/hypermail/linux/kernel/0109.1/0932.html
http://www.xfree86.org/pipermail/xpert/2001-September/011055.html
http://www.xfree86.org/pipermail/xpert/2001-September/011230.html

Is fixed in at least 2.4.9-ac10.  I haven't been a regular user of the 
-ac series so I can't say when exactly this was fixed.  However, this 
problem still persists in Linus 2.4.10-pre10.  Can anyone who chimed in 
with similar problems to mine try said kernel (2.4.9-ac10) and provide 
any feedback?  It would excellent if the exact fix could be identified.

Thanks,

I'm aware of the reports. Its very hard to figure out what might be
involved. Later 2.4 kernels we have fixed the odd possible candidate where
segment registers or LDT propogation on SMP might go awry but nothing that
really explains the X11 ones and whether they are PCI/AGP setup , power
management or kernel bug triggered

I'm using ac-10 with the preempt patch at the moment and still have
trouble with the X server segfaulting sometimes.
Usually it does this not that often (once a day to once every few days),
it seems more likely to happen when switching between text mode console
and X, I can increase the likelyhood of this by running the wmcpu and
wmsysmon applets, which will often make it segfault after only a few minutes.
System is Dual Celeron 433 on an ABIT BP6 board. XFree 4.1.0. Debian
unstable. Riva TNT, using the nv driver. (I sometimes switch to the
nvidia driver because this supports the xvideo extensions, but have not
since the last reboot, so the proprietary module should not have been
loaded)
The most annoying thing is that the console is stuck in graphics mode
after the server crashed...

[Polymorphic Anomaly]

I have had this problem as well, and i finally gave up until i could get a Voodoo
or Rage 128, which have DRM, etc etc. My current card is a savage 4.  After
tryintg all the patches and everything. i finally just disabled the nice
framebuffer consoles so that when X crashes it doesnt take the consoles with it..
does anyone knoe of a real fix?
