as a happy freebsd user since about 2 years I have experienced my first kernel panic and have no idea what to do.

My main machine crashed an hour ago and since then I can't get it to boot.

The panic message:

panic: ffs_clusteralloc: map mismatch
cpuid = 0
KDB: stack backtrace

System setup:

FreeBSD 8.3, up to date
some file system ufs + soft updates
root fs ufs without soft updates
home encrypted via geli
