AHA-2940UW, DLT, alpha & aic driver

[Metod Kozelj]

Hello,

I'm having slight problems while using HP SureStore DLT40 connected to
AHA2940UW on Linux/Alpha.

My system is alpha, running basically RedHat 5.1 with kernel 2.2 patches
and kernel 2.2.14. I'm using stock aic driver.

My problem real problem is, that 'mt -f /dev/nst0 fsf' doesn't do
anything. 'mt -f /dev/nst rewi' works fine, 'mt -f /dev/nst0 status'
prints some meaningful data.

There's some funny thing about /proc/scsi/aic7xxx/0 contents: statisctics
for the DLT never change while statistics for disks do change.

I wonder if the things are better with some recent aic7xxx version?

Here's /proc/scsi/aic7xxx/0:

This is after some reading from DLT. The number of interrupts is quite
high, while statistics show no activity.
