I have a wide device that doesn't seem to be ID'd as such.
System specifics:
Debian GNU/Linux 2.0 (kernel 2.0.35 built myself from source)

SCSI ID 5 - Wide COMPAQ XP32150W

I'm also curious as to why the tape drive doesn't show up in
/proc/scsi/aic7xxx/0? That's probably standard but I was curious.
I just upgraded to 2.0.35 today and applied the pre5 patch right
away. Previously I was having problems with devices not being
recognized every boot (with 2.0.34). Sometimes it was just the tape
drive, other times /dev/sda, with my root FS, and various combinations
varying with almost every boot. That problem SEEMS to have gone away,
which is great! Thanks! I was just puzzled as to why my XP32150W
doesn't seem to be recognized as Wide.
It's not a huge issue. The 32150W is a rather "old" device and the
best I'd expect to get out of it anyway is 6-7MB/s. Still...
Thanks again for the great work!
Gary
