------- Comment #3 from linux@tjworld.net  2008-04-05 09:43 -------
I found a mailing list report of a similar problem where ACPI was the cause.

"kernel-2.6.23.1-30.fc8 problem with symbios scsi controllers"

http://www.redhat.com/archives/rhl-devel-list/2007-October/msg02035.html

That caused me try the boot option "pci=noacpi" and the kernel started. There
are numerous other issues as a result so it doesn't solve the regression since
v2.6.20 but it does narrow down the hunt for the culprit.

In part the v2.6.25-rc8 boot log reports:
