Red Hat Bugzilla – Bug 11716
RedHat 6.2 and 6.1 installation on Alpha does not detect onboard Qlogic ISP1020 Scsi controller
Last modified: 2008-05-01 11:37:55 EDT
I have a Alpha PWS 600au with an onboard Qlogic isp1020 controller and a
pci Qlogic isp1020 controller. The redhat version 6.1 and 6.2 boot images
do not detect the onboard controller. Previously I had redhat 6.0
installed on the system. I installed it using the boot images found at
ftp://ftp.digital.com/pub/DEC/Linux-Alpha/Images. The 2.2.12 kernel on
that disk is able to recognize both controllers. I am able to install
redhat 6.2 from that disk. However when rebooting after the install, the
stock kernel (2.2.14-6.0) that comes with redhat 6.2 does not boot.
Actually it boots but cannot mount the root fs because it has not
recognized the onboard scsi card.
This all occurs even if I remove the pci qlogic controller.
I did not see am updated boot.img from ftp://updates.redhat.com
I have tried the RawHide kernel update 2.2.14-100 and it still does not detect
the onboard scsi adaptor. I upgraded to the 2.2.15 kernel. It detected both
scsi adaptors but I then got a keyboard timeout  error. But the scsi
adaptors were detected just fine. Is there a fix the the keyboard timeout 
problem. I searched the newsgroups and found a few people with that problem
but no answer to it.
I am unable to reproduce this problem in our test lab using 6.2 ...
