Anybody tried booting a -current kernel recently on mac68k?

[Paul Ripke <stix%stix.id.au@localhost>]

I get a hang during startup, with the below backtrace. Note that I
haven't upgraded userland, which is running current from ~2008-04-12.

root file system type: ffs

Panic switch: PC is 0x159912.

I haven't managed to get a dump, but I do note that it's the same
backtrace on every kernel I've tried for the last ~week. I guess
that might suggest there is some sort of cycle in the red-black tree?

This is on a Quadra 605 with full 68040.
