FW: Re: RedHat AS 2.1 (kernel panic)

[ccb at acm.org (Charles C. Bennett, Jr.)]

If your root file system is out the other side of that QLA
it sounds like last kernel update may not have built your
initrd to load the QLA driver before trying to reach for
root.

You can verify by booting an earlier kernel, gunzipping
the suspect initrd and mounting it -o loop and reading
/linuxrc there.

The main cause of a problem like this is kudzu failing
to set up your HBA correctly in modules.conf/modprobe.conf.
You should have a scsi_hostadapter alias there.  Otherwise
mkinitrd isn't hip to the fact that you need it to boot.
