Re: [PATCH 2.6] to get I2O working with Adaptec's zero channel controllers (ASR-2000S, ASR-2005S, ASR-2010S and ASR-2015S)

[Andreas Jellinghaus <aj@leogic.com>]

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.
