I initially filed this on bugzilla.redhat.com, bug number 176994, but they
requested that I move it here.
I have a TYAN S2882-D mobo with two Opteron 250 CPUs, total of 4 Gigs of RAM, 2
Gigs per processor.
The video card is a PNY Nvidia FX 5500 (PCI bus, not AGP if that matters).
I have tried two sound cards, an Ensoniq 1370 and a Creative Audigy 2 ZS. The
problem is the same for either sound card, and doesn't seem to be slot dependent.
If not using sound, the system runs for a day or more. I start using audacity,
recording or playing back, and after a half minute or so, the entire display
freezes up. I can still ping the box, and an ssh from another machine shows the
Xserver at 99.9% CPU. If I kill -9 the Xserver, the box restarts X and I can
It does the same thing with gcdmaster playing back a wav file. So it looks to
be an interaction between X and a sound card.
I did an strace on the Xserver, but I'm not sure it is meaningful - it reports
a buffer overflow in select, which I've seen listed in another bug as due to
tracing a 32-bit app on a 64-bit system. I'll attach the trace anyway in case
it is helpful.
I can reproduce this 100% of the time on this machine, and I will gladly capture
any other data anyone might like to see.
Steps to Reproduce:
Actual Results: Screen freezes, Xserver goes to 99.9% CPU
I tried installing the proprietary nvidia driver:
and the problem completely disappears. So, I am currently suspecting the xorg

Installed the latest Fedora Core 5, with Xorg 7.0.0. This bug appears to be
fixed in this version.
Mass reopen. The "LATER" resolution is lame, I'm deleting it. Consider LATER to have arrived.

I'll close this then. Reopen if the problem shows up again in a newer Xorg.
