panic with UFS_DIRHASH

[Fekete Zoltán <fekete.zoltan%minux.hu@localhost>]

Hi There,

I have just built my own kernel in -current.
It seems that there is a panic on certain directory operations. I 
experienced in the install phase of a slightly large package with pkgin.
Last call on the stack is ufsdirhash_findslot().

The panic causes also filesystem corruption.

See my stacktrace image here shot by a phone, sorry for the dusty 
screen, it's a workhorse...
