I been having problems reading a tape on our new DDS-3 tape drive
(a sony SDT-9000). The tape in question has a large file on it (1GB
or so) and about 460MB into reading the file everything goes to hell
on the scsi bus.
Here's the output from the kernel:
sd0(ahc0:0:0): SCB 0x7 - timed out in datain phase, SCSISIGI == 0x44
SEQADDR = 0x124 SCSISEQ = 0x12 SSTAT0 = 0x0 SSTAT1 = 0x2

The system is 2.2-STABLE as of August 26th. I also tried the
2.2-RELEASE GENERIC kernel for good measure though and the exact same
problem occurs. Any ideas as to what might be going on? I've been
able to read a bunch of other tapes (15+) without problems, but this
particular tape just dosen't want to be read. =(
thanks,
steve
