Linux problems with Syquest EZ-135 Scsi external drive

[hein at zack.radex.plh.af.mil (Carl Hein)]

If I attach a Syqeset EZ-135 to my Linux System (Slackware kernel 1.2.13,
Adaptek 2842 controller (local bus)), I have experience multiple system
crashes, particularly when transferring large files. The symptoms of the
problem are similar to previous kernels (using the same controller), which, 
when I removed the controller and replace with a 1542B contoller when away
(kernel was compiled would support both 1542 and 2842 controllers). Tjhe[2
The previous problem occurred with slower (SCSI I drives, such as Maxtor LXT213-S). With a previous upgrade, this problem disappeared, but I had problems
(crashes) using a NEC CD-ROM reader (model 81?). 

With kernel 2.1.13 both problems went away, but similar symptoms occur when
I try to use the Syquest EZ-135, either for DOS or Linux formatted disks.
I am able to use the Syqest on my home system (Kernel 2.0.8, Adaptek 1542B
controller), without this problem, but I get a warning message on boot if
a disk is not present when I boot.

Any solutions?
