It seems that integration of async stuff broke normal stuff somehow :-( I restore my 10 days old kernel and all works right again. It looks like the same problem which manifistated in 3 states: 1) Singe process hangs in "getblk". No signal reactions occurse. If I attempt to read the same blocks from other process, first one unhangs. 2) All process which attemts to read/write UFS hangs forever. 3) Disksort panic. -- Andrey A.
