Probably has something to do with the translation overhaul:

Mutex error: mutex_vector_enter,543: locking against myself

lock address : 0x00000000007568c0
current cpu  :                 0
current lwp  : 0x0000000000751080
owner field  : 0x0000000000751080 wait/spin: 0/0
This was done with the install kernel...
boot cd:,\OFWBOOT.XCF;1

I'll take a look.  I'm skeptical that it's related to early bootstrap
changes, but you never know.

 FYI, kernel, bootloader, and userland (built from -current as of
 few hours ago) work fine for my Mac mini G4, as far as I can see.

 Details for panic, i.e., machine, situation, etc. should be helpful.
