Hello,
I am experiencing consistent lockups of the linux kernel when I play chess
with crafty. What happens is that while the chess engine is running,
suddenly the whole system will freeze, and the only think I can get to
work is the reboot button. I have tried to put the computer in text-mode
(telinit 3) and run the chess program (with gui) from another computer on
my LAN, to see if any oops-output would show up, but there is nothing.
My system runs Redhat 7.2 and is uptodate with patches (so I'm running
kernel version 2.4.20-24.7 #1, athlon version). The chess program is
Crafty 17.9. The processor is "AMD Athlon(tm) 4 Processor".
/var/log/messages shows nothing of interest.
I wonder if this scarse information is good for anything. And in any
case, thanks for all your great work which I benefit from every day!!

Could this be a simple overheating problem?
Chess programs are cpu intensive, and so the cpu gets hot.
Perhaps there is insufficient cooling. the cooling may be
enough for non-cpu intensive stuff like email, web, and so on.
what happens if you run a big compile or a long-lasting
cpu benchmark? Those things also cause heat.

Thanks for your reply! I have had math programs running for several days
in the past and never experienced any lockups, so I doubt that overheating
is the problem. To make sure, I just did "while true; make clean; make;
done" to the linux kernel in a couple of windows, unpacking / deleting in
another, math programs, etc. for a while, without any problems. (CPU
usage was > 99%.)
In the first message I forgot to say that ping from another computer gives
nothing when the frozen one is frozen.
Also, please cc [email protected] (as you did, thanks!) since I'm not on the
lkml.
