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

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.

I'm still trying to narrow this down a bit...

It seems that if I rebuild a kernel from sources as of 2009-11-09 17:00 UTC, the system boots. Yet a kernel from sources updated to just one hour later, at 18:00 UTC, fails. The only commit during that interval was the update of sys/sys/param.h from 5.99.21 to 5.99.22 - no other source files updated!

The target system has both 5.99.21 and 5.99.22 modules in /stand/amd64/ and the same 5.99.22 modules work on all my other Intel and AMD CPUs. The modules are built from yesterday's (2009-12-17) sources.

I guess I can do a binary search to figure out when the modules broke...

What module(s) would be loaded at such an early part of the system boot?
