 Actually, I suspect your issues should be fixed by this patch:

 Could you download 2.6.24 and try it out to see if they are?

 Thanks,

Well, 2.6.24 fixes the problem.
Thanks to all of you!

  Yes it works under 2.6.16.13.  See the beginning of this thread, i
  mention there some things about newer versions.

 Thanks, actually, I see this:

  I tried to install OpenSUSE 10.3 (kernel 2.6.22.5) and the latest
  OpenSUSE 11.0 Alpha 0  (kernel 2.6.24-rc4) but although the initio
  drivergets loaded during the installation process, yast reports that no hard
  disk is found.

 Could you try with a vanilla 2.6.22 kernel?  The reason for all of this
 is that 2.6.22 predates Alan's conversion of this driver (which was my
 95% candidate for the source of the bug).  I want you to try the vanilla
 kernel just in case the opensuse one contains a backport.


Yes you are right. I compiled the vanilla 2.6.22 and initio driver works.
Tell me if you want to apply any patch to it.



 Thanks,

 James

 I think there's still one remaining bug from the sg_list conversion,
 namely that cblk-sglen is never set, but it is used to count the number
 of elements in the sg array.  Could you try this patch (on top of
 everything else) and see if the problem is finally fixed?

I tried patch[2] (addition of   sg++)  at 2.6.24-rc5-mm1 but the
system hangs after some seconds when the initio driver loads.
I will try patch[1] next week to see what happens.

Would it be better to open a bug report at bugzilla?

  in the initio scsi driver because i also tried to install Fedora 8

  I have seen the relevant thread Conflict when loading initio driver
  and i suppose that the initio driver isnt fixed yet.
  I can help testing the new patches in the initio driver if someone is
  interested.

 initio doesn't seem to have a maintainer...

 Are you able to identify any earlier kernel which worked OK?


I have this PC configuration since 2002. The initio driver worked
perfectly with 2.4 kernel series.
With the release of 2.6 kernel series the driver had been marked as
BROKEN and fixed at 2.6.9
(see at 
http://www.gossamer-threads.com/lists/linux/kernel/482582?search_string=SCSI%20updates%20for%202.6.9;#482582
  Christoph Hellwig  -don't mark the initio 9100 driver broken)


 Maybe it's a new device?  If you can get the `lspci -vvxx' output
 for that device we can take a look.


No its not a new device.
