Hello everyboydy,
the current 7.1b kernel (2.2.15-1mdkfb) is buggy!!!
I wanted to transfre some data brom a friends computer to mine via zip.
We both ran 2.2.15-1 from 7.1b (me: mdkfb; him: mdk).
In both machines the scsi-zip drive aborted with a hang :-( the kernel
tried several times to reset the scsi-bus without any success :-(
Attached "/proc/scsi/scsi/" and "/proc/scsi/aic7xxx/0" and some kernel debug
output from my working kernel (2.2.14-15mdkfb) and from the buggy
(2.2.15-1mdkfb) one.
Mail me if you need other informations ...
