Description lehi k davis 2008-03-25 18:54:14 EDT
Description of problem:
Doing optical drive intensive operations (burning DVD/CD, playing back video
from DVD/CD) causes the machine to slow down to an unusable state.  For example,
playing an unencryped DVD with mplayer, mplayer will report that the system is
too slow and drop frames.   Burning data to a DVD+RW slowed the system down so
much, it took over 3 minutes for window focus to change after clicking on a
different window.

Version-Release number of selected component (if applicable):

How reproducible:
Every time.   

Steps to Reproduce:
1. Boot from kernel-
2. attempt to burn data to cd/DVD
Actual results:
System slows to an unusable state

Expected results:
maybe 30% cpu utilization, and normal operation from there

Additional info:
I went back kernel- and everything works fine again.

Please post the boot messages (file /var/log/dmesg) from booting the 2.6.24 kernel.
