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've been happily running my Core i7 920 in a 5.99.21 kernel (sources dated 2009-10-24 18:29:38 UTC) with no issues.

Today, I tried updating to a 5.99.22 kernel (sources dated 2009-12-16 14:17:30 UTC), and the kernel refuses to boot. Very early on, it simply does a hard-reboot, much too soon for me to capture what it might be saying. I tried to 'boot -d' into KDB, but when it hits the initial break-point it goes into an apparently infinite loop printing "Symbol not found" (stopping at the bottom of every pageful of output!) and never gets to a prompt.

Here's the 'cpuctl identify' from the Core i7:

The dmesg from the 5.99.21 kernel is attached.

Anyone have any clue on what may have broken? None of my other machines have any problem with their own kernels built from the same sources. (The "other" machines include various amd dual- and quad-core processors as well as a Intel Core-2 Quad-core Q6600.)
