Hi,

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
#0 0xffffffff8063dcbe at kdb_backtrace+0x5e
#1 0xffffffff8060aed7 at panic+0x187
#2 0xffffffff8082c1df at ffs_clusteralloc+0x4cf
#3 0xffffffff80828448 at ffs_hashalloc+0x28
#4 0xffffffff80829a31 at ffs_reallocblks+0x421
#5 0xffffffff8068accf at cluster_write+0x4df
#6 0xffffffff8084a1cf at ffs_write+0x58f
#7 0xffffffff8097e6a2 at VOP_WRITE_APV+0xb2
#8 0xffffffff806a9f23 at vn_write+0x373
#9 0xffffffff8064dceb at dofilewrite+0x8b
#10 0xffffffff8064e000 at kern_writev+0x60
#11 0xffffffff8064e085 at write+0x55
#12 0xffffffff809000c4 at amd64_syscall+0x1f4
#13 0xffffffff808e8a6c at Xfast_syscall+0xfc

System setup:

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

Regards,

Jens
