Sorry it's taken me a while to respond, I've been out on family leave. I have tried as you suggested, booting from the open firmware screen instead of directly from the CD, and I get the same result. I downloaded and burned the 6.0RC1 ISO this morning, and get a slightly different error, but in the same place. The error now reads: KDB: debugger backends: ddb KDB: current backend: ddb Panic: Assertion curthread != NULL failed at /usr/src/sys/kern/kern_mutex.c:268 KDB: enter: panic [thread pid -1 tid 0 ] Stopped at 0: illegal instruction 0 Db> I can't interact with the system at this point to run a stack trace. Any ideas? Oh, and no, it's not an eMac. It's a PowerMac G4 667mhz w/ 256 megs ram. This same machine runs fine under OSX. Tim Simmons IT Technician Champion Realty, Inc.

Thanks. Would that be an eMac by any chance ? :) I've yet to get to the bottom of this, though I have an idea or two as to why it's happening. In the meantime, the workaround (at least on my ageing eMac), is to break into OpenFirmware (cmd-opt-o-f at the boot chime) and manually boot from the OpenFirmware prompt 0 > boot cd:,\boot\loader cd:0 later, Peter.
