 Has happened twice to me with an AHA 2940 and an Exabyte 8200.
 Did not happen on my prior 2.1.6? version, but
 happens now in my 2.2.1-RELEASE version.
 
 No error messages, system just freezes.
 The last things I see in the log are the "normal" error messages
 Oct 15 20:42:53 jbr /kernel: st0(ahc0:5:0): Target Busy
 which I believe is due to a out-of-date firmware on the Exabyte.
 Has never caused a crash before.
 
 Seems to occur mid-tape correlating to some audible tape motion
 command (Click!).  
 
 I don't have the sequence of events, but I had another crash
 using the AHA 2940 with a CD-ROM writer (Phillips CDD 2000).  Has
 not happened again.
