crash

[pb]

Hi,

I hope I am not offtopic, but I don't have any better ideas 
where I could ask ...

I've a 2940u2w, and a yamaha cdrw8424s, well and the only resuts I get
is, that the system crashes or the scsi part is still unusable after un
usage about half an hour ... ie about half an hour all works fine, but
than I just get timeout und bus errors und the thing hangs ... 
all the tips I got from usenet or mailinglist were to check termination
cables etc ... but imho that's not the problem coz as mentioned for about
half an hour the drive works just fine ... 
maybe anyone on here has any ideas what I could try coz I've tried many
things ... installed kernel 2.2.15 patched the aic7xxx driver from 
5.1.28 -> 5.1.29 and played arround with other things and settings, but
didn't get any positive resluts ... 

here some example logs,

about half an hour fine )

It's trivial to make fun of Microsoft products, but it takes a real 
man to make them work, and a god to make them do anything useful.
