Nope, cut the "panic" message from the log and do:
  cat panic_messages | ksymoops

But... I just looked to confirm where ksymoops is installed and did not
find it (I have not used it in a while). 

It turns out that it is no longer part of the kernel, see:
(if you have the kernel-source package installed). 

You can find the sources to ksymoops at:
I should probably create a package. Anyway, this will not solve your
problem, just make a potential debug easier for a guru.

A second kernel, you can install it by installing
planetccrma-core-redhat. Again, my guess is that this is an alsa problem
with your particular soundcard so this probably will not help. 

Another option you can try is to install a test alsa driver that is
newer than the stock one at Planet CCRMA. See this thread for


Best luck...
