I'm running out of ideas so I'm turning back to the list for help, what
I have tried:
3 different SCSI cards (Adaptec 2940, 2940UA, and 29320A)
3 different tape drives (2 DLT drives 20/40, 15/30, and an exabyte 8mm 7/15)
with one exception, the 29320A controller timed out waiting for the
exabyte to come ready, the exabyte takes forever and a day and has been
a problem in the past because of long wait until ready.
All controllers recognized all drives with their (the controllers) built
in bios, All drives were recognized under linux as was seen in the
/proc/scsi/aic7xxx/0 file. All drives were listed in dmesg. Each drive
was tried with each controller and the same results.
anytime the command "mt -f /dev/st0 stat" was issued the command just
hung, I would be unable to kill the processes with a kill -9 as well.
If I let the system sit in that state long enough the whole system would
become unstable and not respond.
What I do know..
1) All three controllers work fine
2) All three tape drives work fine (sans the long delay to ready on the
exabyte)
3) I have no entries in the /etc/modprobe.conf
4) There is a USB flash card reader in the system that also shows up as SCSI
dmesg output (scsi related sections - includes a lot of USB stuff
since the USB flash drive shows as scsi controller 1)

Ok, just tried another tape drive same deal, when I attempt to access the
drive with "mt -f /dev/st0 stat" the command hangs, I'm unable to kill the
process either (same as before)

You are right, its "st" and it shows up
scsi_transport_spi 25281 1 aic7xxx
scsi_mod 134761 6
sd_mod,usb_storage,st,sg,aic7xxx,scsi_transport_spi
also dmesg shows the following entries:
scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 7.0

and then further down:
scsi 0:0:6:0: Attached scsi generic sg0 type 1
st: Version 20050830, fixed bufsize 32768, s/g segs 256
st 0:0:6:0: Attached scsi tape st0
st0: try direct i/o: yes (alignment 512 B)
So the system definitely sees the controller and tape drive, just any IO
to it hangs. I'm wondering, do I have a good drive?

When I send any commands to /dev/st0 the application just sits there, a

lsmod does not show the "mt" device, should it be there and if so, how
do
I load it?
I have a dat tape on a scsi controller on an fc5 system and I don't see
an 'mt' module loaded using lsmod.
