After cvsup'ing last night, a kernel built with INVARIANTS panics on boot
with:
panic: biodone: bp 0xc0b5b600 not busy 0
Debugger("panic")

Removing INVARIANTS and INVARIANTS_SUPPORT gives a bootable system. This is
a regression since ~March 12 (I think that was my last cvsup). The exact
kernel config is:
