Sorry for not responding sooner...work...It seems to be a random issue that doesn't show up in a logcat. It seems to happen only when inserting or removing a cd/dvd and does not happen with any USB devices (hdds, thumbdrives, cd-roms). The stock DVD-R/W drive is a Sony and the other I have tried is a Toshiba. Both create the same panic. I will check the mount to ensure it's not mounting as a hdd and causing the error that way, but it's not a constant issue, sometimes it can be 3 or 4 months between issues and sometimes it's 3 or 4 times in a day, depending upon how much i'm using the drive.
