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. -Brandon
