On my Linux 2.0.35/SMP driver Dual PPro box I got the following after
loading and unloading the ncr53c8xx device driver a few times:

There was another scsi driver loaded for the ZIP drive (PPA 1.42) and it was
copying data from the zip disk to the ide harddisk.
Is it such a bad idea to (un)load a driver on a working system (copying
data) ?
In a second try, the machine didn't behave nice after unloading this driver.
I halted it immediately after that to avoid trouble. I can't see what is
really going on because there is no console on the box. I use it remotely.
I hope someone can shine his light on this.
Bas.
