I did a reboot, which ended up hanging... I had to forcefully reboot as
it seems the reboot process must not have liked that lingering request.
I booted up, and I got the same error when the CD was in the drive...
I've not had issues with other CDs, nor did I have an issue till I
ripped the first 8 tracks of this one... that's when everything went
wrong. I'll try the sysctl stuff mentioned before.
