Re: linux 2.6.9 on alpha noritake

Hallo Ivan,

that seems to do the trick....
but as usually one thing fixed next broken....
now the sym53c8xx won't scan the SCSI bus.
So I have no chance to boot and take a closer look if everything is
working again. I do further investigation later on.

Thank you for your help!
Alex
