>Description:
With the upgrades to 3.0-REL, the scsi cards (Buslogic BT948s) started
to hang and report timeouts in the kernel on all (3) of the machines with the 
combination of BT948 cards and 3.0-REL or newer (up to 3.2)  Here is a kernel message:
(da0:bt0:0:0:0): CCB 0xc5548500 - timed out
(da0:bt0:0:0:0): CCB 0xc5548500 - timed out
bt0: No longer in timeout
(da0:bt0:0:0:0): CCB 0xc55487c0 - timed out
(da0:bt0:0:0:0): CCB 0xc55487c0 - timed out
bt0: No longer in timeout
(da0:bt0:0:0:0): CCB 0xc5549840 - timed out
(da0:bt0:0:0:0): CCB 0xc5549840 - timed out
bt0: No longer in timeout
(da0:bt0:0:0:0): CCB 0xc5548a80 - timed out
(da0:bt0:0:0:0): CCB 0xc5548a80 - timed out
bt0: No longer in timeout
(da0:bt0:0:0:0): CCB 0xc554a1c0 - timed out
(da0:bt0:0:0:0): CCB 0xc554a1c0 - timed out
bt0: No longer in timeout     
During the timeout no disk access is available, and timeouts last from 
10 to 30 seconds, during which keyboard and mouse inputs are queued
up and all execute upon disk being available again.  I posted this problem
in December?? when 3.0-REL was out and was told to install a newer SNAP
as it was a recognized problem and the newer code fixed it., problem persists
to this day on some very current 3.2 machines.
>How-To-Repeat:
do something with a fair amount of disk access (download the ports collection,
serve content, etc.)

 Hi,
 
 I've experienced similar problems with a BT 946C
 (1995).
 As the 'hanging' SCSI ID displayed always referred to
 the second harddisk, I thought, I have a problem with 
 that one. So I sucked the data as long as it worked,
 and bought a new one (updated the System in between,
 so that it runs currently a 3.2-STABLE). But the
 problems still occur, just less often.
 No worries for the additional harddisk, i would
 have needed it anyway, but then I thougth about
 buying a new hostadapter. Well if it could
 be problem with the driver, and it seems that way,
 I would save that. :-)
 
 Cheers,
  Daniel
