Hello,
the patch should get the mentioned controllers working with the I2O
subsystem. Because we have no hardware to test it on, it would be great,
if someone could give it a try and report if it works or not.
We've tested it on i686 and x86_64 with already working I2O controllers
without a problem.
Thank you very much.
Best regards,
Markus Lidel

not my 2010s. it is not found at all. I send details to markus
as a direct mail (sample config, dmesg, lspci -vvv).
Does anyone else have success using this patch?
(I used it with kernel 2.6.7-rc1 btw, I hope that was ok?)

Hello,
this patch now gets the mentioned controllers working with the I2O
subsystem. It tested on two different system with ASR-2005S and
ASR-2010S and reported as working.
It's also tested on i686 and x86_64 with already working I2O controllers
without a problem.
Thank you very much.
Best regards,
Markus Lidel

To: linux-scsi
With that patch and 2.6.7-rc1 I can
use the apaptec zero channel controller fine.
But: once I stress the i/o with a simple
time dd if=test of=test2 bs=1M
after some minutes the i/o stops:

here the vmstat freezes. This test was with elevator=deadline,
earlier test without had the same problem.

with some tests I had a shell open while the dd i/o froze,
and thus I can say: dmesg did not report any errors, it had
only the boot log.
also below is the kernel config.
I will now try 2.6.7rc3 with the dpt driver.
the machines work very fine with 2.4. and the dpt driver...
if you want a full dmesg or to test something, please
let me know.
