(I'm sorry if you get this twice, but I send it out two days ago,
for some strange reason this message is not in the archives, which seem
to work now, and I didn't recieve any reply).

Hi,

I managed to get the 2.6.0-test5 kernel to work (Andrey: the part with
the VGA-Console still isn't right in test5! I had to apply your patch
for test3 manualy to make a console appear).

The qla1280 driver compiles now and recognizes my harddisk! Hurray *g*
Still something is wrong - during start-up the driver displays the
following stuff:

That looks pretty wrong to me. However I ignored it, created partitions
on the my SCSI drive, and tried to migrate my stuff from my ide drive to
the SCSI drive. The copying went pretty slow and halted frequently for
some time. After maybe 130 mb it haltet completly. I rebooted and tried
again. This time maybe after 400 megs I got this wonderful stack trace
and kernel panic:

btw. this is typed in manually. *cough*. It might contain typos.

I this a visws-issue (messy interrupt handling stuff?) or is something
in the qla1280 driver defunct?

Ciao
