I don`t think that it is a problem of the scanner. It is a known problem caused by
termination, cable or scsi-driver problems.

The scanner does not do any termination. You mean the termination that came with
the scanner? That is a passive one. If you work with a fast scsi card that should be ok,
for an ultra scsi card you should use an active one.

YES, YOU NEED TO!
Normally there are jumpers or resistor arrays on the scsi card or the termination
can be activated via the bios. Some cards automatically activate the termination
but you really have to make sure it is terminated!!!

The driver is responsible to turn out the light for the astra 2200, but I don`t have
the command sequence for that.
In the moment: pull the power connector to turn off the scanner.
It also may be a problem of the scsi driver of your scsi cards.
Lots of 1.x.x kernels had buggy scsi drivers. The 2.2.x kernel should be ok
for the most scsi cards, so the 2.3.x also should be ok. But when the scsi card is a
new product the driver may also be new and buggy.
