PANIC: ffs_blkfree: bad size

[Marc G. Fournier]

Is there any way of determining *what* is causing this, based on the 
information that I'm getting on the console? :(

dev=#da/0x20007, bno = 671547887, bsize = 16384, size = 16384, fs = /vm
panic: ffs_blkfree: bad size
mp_lock = 02000001; cpuid = 2; lapic.id = 06000000
boot() called on cpu#2

Thanks ...
