FW: Red Hat 7.3 - kernel and st driver

> I've got a Compaq (HP) DL380G2 running RH7.3 with an Adaptec2940 card in

> with an HP LTO tape drive.  It was running the default kernel
> (2.4.18-3smp)
> on it until recently.  I've always had problems with the attached tape
> drive.  After a reboot I would have to run "/sbin/modprobe
> scsi_hostadapter1" to get it to find the tape drive and add it as a
> device.
