Comment 4 for bug 653815

This bug affects me, using lucid with a backported karmic kernel from ppa:kernel-ppa/ppa (workaround for dreaded intel video lockups with lucid kernel)

Other than that, I have the same configuration and symptoms:

 * brief X and sound stutter every 10s
 * corresponds to a spike in kslowd activity
 * intel 855GM chipset

Trying the .36 kernel Jonathan had success with (I know this is completely unsupported, just not ready to jump to karmic userspace yet)
