I don't use async mounts, but have getblk hangs.

I use pure UFS only, but have getblk hangs.
Some more info: in rare cases getblk hangs can be cured by accesing
the same disk blocks from another program. In rare cases getblk
hangs cause panic in disksort. Kernel from Oct 1 works fine for me.
Someone else reports that kernel from Oct 6 works fine too.
