Re: Boot failure - port-amd64 on Intel Core i7 920

[Paul Goyette <paul%whooppee.com@localhost>]

Since another poster on this list indicated that a kernel compiled 
without options ENHANCED_SPEEDSTEP and INTEL_CORETEMP enabled his Core 
i7 to boot, I gave it a try today.  On my machine, the boot still fails 
very early on, and it reboots so quickly that I am unable to get even 
the briefest glimpse of what messages might be displayed.

Any additional clues would be greatly appreciated.
