Hi Justin !
First of all, thanks for your work in the cam driver it really
looks very promising and it solved the write append error with
my TDC 4222, 'though I still don't have amanda running, but
that's another story ;-)
I made the following observations with the cam driver (980103 Snapshot)
on a -current from exactly that date:
On system halt or reboot it happens, that the following
message is printed on the console multiple times:
Timedout SCB handeled by another timeout.
Timedout SCB handeled by another timeout.
Timedout SCB handeled by another timeout.
...
When the system comes up, then about 10 or 20 files will be deleted
from fsck -p. I think these are only tmp files.
My machine is a SMP machine.
I have two SCSI controllers:
T- ahc0 - ID 0 - IBM DORS 32160
ahc0 - ID 4 - TDC 4222
ahc0 - ID 6 - CD-ROM - T
T- ahc1 - ID 1 - IBM DORS 32160 ccd 0
ahc1 - ID 2 - IBM DORS 32160 -T - 3
Here what dmesg tells about my system:
Additionally I have strange problems with my Tandberg SCSI streamer.
mt status only tells one density.
Present Mode: Density = 0x00 Blocksize = 512 bytes
---------available modes---------
Mode 0: Density = 0x00 Blocksize = 512 bytes
Mode 1: Density = 0x00 Blocksize = 512 bytes
Mode 2: Density = 0x00 Blocksize = 512 bytes
Mode 3: Density = 0x00 Blocksize = 512 bytes
Sometimes a dump doesn't finish.
