Equally sadly I'm no kernel programmer so my attempt to chase down the panic by looking at the current rev of kern_mutex.c didn't yield anything. A pity because I'd like to get FreeBSD working on this machine and then see if any userland needs tweaking (my C skills do at least run that far) - so if there's any way I can help track down this problem I'd like to do that.

Could I use that to attack the kernel problem? How would I build the FreeBSD kernel under Darwin? Cheers, Graham. [enthusiastic, if somewhat out of depth]
