Ok, after 3 successfull "make world"s yesterday with no problems, the
machine crashed last night during a "make release". The messages on
the console:

--------
setup_allocindir_phase2: need bmap, blk -12
setup_allocindir_phase2: need bmap, blk -12
setup_allocindir_phase2: need bmap, blk -12
setup_allocindir_phase2: need bmap, blk -12
dev = 0x40c, block = 5832, fs = /a
panic: ffs_blkfree: freeing free block
mp_lock = 00000001; cpuid = 0; lapic.id = 01000000
Debugger("panic")
Stopped at      _Debugger+0x35: movb    $0,_in_Debugger.96

where in gdb show the folling:
