I don't usually weigh in on these things, but for what its worth, I'm 
still having problems with FC4 and planetCCRMA.

The planetCCRMA smp kernels still don't boot for me, and unfortunately 
I don't have time/patience/expertise to start recompiling the kernel. 
The uni-processor ones boot, but crash after awhile. I'm back to using 
RedHat's latest smp kernel.

Not totally sure how to investigate the crashes with the CCRMA kernel. I 
don't use the machine all the time, but if I leave it running for more 
than an hour or so, its normally frozen with a blank screen when I come 
back to it. I looked in /var/log/messages, and the only notable difference 
between the RH and CCRMA kernels is that with the CCRMA kernel I get the 
messages copied below periodically. When the machine freezes, there is 
one crond job after these messages, and then nothing. But it doesn't 
freeze everytime these messages appear.
