Description of problem:
On a bordeaux w/ a02 bios, 32GB ram, perc 3/qc, intel 1000/XT, and qlogic 2200.
While installing pensacola ia64 qa1108, VT4 reports "Kernel panic: Invalid

2. Note kernel panic after loading of qla2x00 driver
Actual Results: Install kernel panics after loading qla2x00
Expected Results: Normal install

Correction, I saw a "kernel panic: Invalid or not present host" error during one
of five successive boots. Error appeared after "starting sendmail" during
service starts. The four other boots were without error. Once again, this is
Did 2.4.9-13.4 make a difference? I saw you tested 13.4 on this platform
on bug #55833
Please test again with the new qla2200 driver in the latest tree we
Is this direct-attached or attached through a switch?
Does not occur during install of qa1129 (2.4.9-17.3smp).
Also, have not seen during subsequent boots.
Storage is direct-attached.
Good, it sounds fixed. Thanks.
