this is marked as broken in the upstream kernel, as no-one bothered to convert
it to use new dma-mapping code that came about in 2.5.  Your best bet is
probably to ask the folks upstream on the linux-scsi@vger.kernel.org list
whether it's being worked on, or left to bitrot.
Comment 2 Steve Bergman 2004-11-28 03:53:12 EST
2.5?  The module exists in Fedora Core 2 up through 2.6.6-1.435, though it does
seem to be missing from 2.6.7-1.494.2.2 and  2.6.8-1.521.  Or did this change
occur in 2.6.7?  Are drivers getting broken in the stable kernel series?
Comment 3 Dave Jones 2004-11-29 01:03:05 EST
in 2.6.0 -> 2.6.7 it wasnt marked as broken, though it could corrupt data due to
a missing/broken conversion to the dma-mapping code.  It was then correctly
marked as broken later.
Comment 4 Steve Bergman 2004-11-29 12:44:44 EST
OK. Thanks.  I was going to compile up a kernel with support, but if
it can corrupt data... this is used for our tape backups.  Time for a
new SCSI HA.  

Too bad about Advansys.  They were a good company and one of the
earlier players supporting Linux.  I believe they wrote the drivers in
house, made them open source, and supported them officially.
Comment 5 Dave Jones 2005-01-14 02:09:29 EST
Aparently this is safe to enable on x86 even though its broken on other
architectures. I've fixed this in CVS, it'll go out in the next update.
