Hi Bryan.

 =>From: Bryan Chambers <[EMAIL PROTECTED]>
 =>...
 =>The Accelerated-X server 5.0.3 has not been tested
 =>on and does not support 2.3.x kernels.  Have you
 =>seen this problem on a supported 2.2.x kernel?

Yes, I recently reinstalled the system with RH6.2, and it happened
even with the stock 2.2.14-5.0 kernel.  (The symptoms -- erratic mouse
movement -- were the same, anyway.  I don't know for sure that it was
the 8253 time constant getting whacked.)

 =>Also,
 =>have you tried disabling one of your processors; I've
 =>seen SMP systems mess with the clock before.

That's a good idea. [...save buffer, reboot nosmp ... continue] I'm
now running on a single CPU, and the problem hasn't exhibited yet
(kernel is 2.3.99pre9).

 =>Finally, did you not have this problem with XFree; is that why
 =>you claim it's related to our server?

I haven't run XFree for a year or two; when I installed your server, I
started having clock problems (you may remember my messages from a
while back :-).  At the time, I tried reverting to XFree and still had
trouble, but I didn't know enough about the libraries to be sure I was
running 100% XFree, and not some portions of your code through the
shared objects.  Besides, Xaccel was so much faster that I was
motivated to fix the time problem in the kernel so that I could keep
using it.  (And I did, in fact, perpetrate a kernel hack that allowed
me to run with Xaccel.)

Anyway, I don't believe the problem is specifically with the Xaccel
server, but only that the server drives the kernel and/or hardware in
a way that causes the problem to exhibit.  I mentioned it only because
it's the one really unusual thing that might make the difference
between an SMP guru being able to repro my bug or not.  (Many people
have Voodoo3 graphics cards, some have dual-proc boxes, a few have
N440BX motherboards, but how many have all that and Xaccel, too?
Probably only me!)

So I'll live with my kernel hack for another few linux releases (it
really works fine!) and then probably be inspired to fiddle with it
again.   Meantime, maybe somebody else will find this message in an
archive and get the clue he needs to solve his own time problem.

Regards,
d.
