For the last 3-5 days (since about the time of detachable devices ?),
current kernels on my Quadra 610 have been unusable. They die,
typically with 'Panic: MMU fault trap" during rc file processing.

I have seen it die in fsck, in usb, and to day in sh.

This kernel was made with a fresh config, then
make depend&&make clean&&make.

A ddb traceback from a few minutes ago says:
