I know this is an old one, but I'm running 10 and I'm still getting this 
problem.

kernel: panic: ufs_dirrem: Bad link count 2 on parent
kernel: cpuid = 1
kernel: KDB: stack backtrace:
kernel: #0 0xffffffff808e7e90 at kdb_backtrace+0x60
kernel: #1 0xffffffff808af975 at panic+0x155
kernel: #2 0xffffffff80afe7d7 at ufs_rmdir+0x1d7
kernel: #3 0xffffffff80d994f8 at VOP_RMDIR_APV+0x98
kernel: #4 0xffffffff80952a68 at kern_rmdirat+0x1b8
kernel: #5 0xffffffff80c8f127 at amd64_syscall+0x357
kernel: #6 0xffffffff80c7581b at Xfast_syscall+0xfb
kernel: Uptime: 2h36m59s

Is there a fix or one in the works at all? This also not the first time 
I've had this issue crop up since I've been running 10. I am using ssd 
hdds if that helps.
