If I disconnect the drive the computer boots fine. If the drive is connected, it panics like this somewhere in the middle of the boot process. (Of course only after mounting the partitions) If I connect the drive while the system is running, I get the same panic. I do not have access to more debug information at the moment, but will try to gather some tomorrow. The system configuration is AMD XP1800+, 512Mb of RAM, KT600 chipset. All system frequencies are appropriate and nothing is overclocked anywhere in the system. -- Erik H. Bakke
