I'm not sure when this started, but the more recent kernels don't seem
to be able to keep up with my TK70. Reading or writing involves a lot
of 'shuffling' instead of a constant write.
Cleaned the drive, used new tapes.. Didn't help..
The rest of the box should be able to keep up fine:
KA650
32 Mbyte
Emulex UC07 SCSI controller
HP 2 Gb SCSI drive
TKQ70 controller with TK70 drive
Older kernels (1.2 and friends) could keep it going in one continuous
write. It's about the only area in which Ultrix is better ;-)
It's not critical as it ultimately _does_ work. It's just veeeeery sloooow..
Bye Arno.
