Hopefully this should resolve the outstanding initio failures.
Patch is available here:
master.kernel.org:/pub/scm/linux/kernel/git/jejb/scsi-rc-fixes-2.6.git
Full patch attached.

Subject: [SCSI] initio: fix module hangs on loading
I've verified (on my Initio 9100 with a DAT drive) that the
2.6.24-rc8-git6 initio module still hangs on loading.
These fixes (other than the printk) are needed to get the module to load
ok (and work correctly) with my adapter & tape drive.
a) printk cosmetic fix
b) cblk->sglen needs setting for later DMA I/O routines to use
c) host->bios_addr needs setting for debug output correctness
d) semaph & semaph_lock initialisation had got lost since 2.6.22
e) since 2.6.22 the bios data address was truncated to 16 bits (needs 20
when shifted left)
