Hello list, I was trying to use a newer kernel on a gentoo installation, and 
I've downloaded a lastest kernel 2.6.17/16 getting a hardlock on boot time, 
with or without smp mode, controlled by BIOS or by smp kernel option I got 1 
penguin or 2 penguins as processors get detected, it just hang after frame 
buffer or agp detection, but using vga=0 to not see any frame buffer I got a 
so faster oops and kernel panic and machine reboots, then I can't see 
anything on the screen, just with frame buffer enabled, but with frame buffer 
enabled does not work SySREQ, is just a hang.

Attached .config file used, cat /proc/cpuinfo with 2.6.11 that was the kernel 
that can be built for, and lspci, and verbose lspci.

The config file is the same used for the tests, with or without frame buffer 
enabled is the same.

BIOS VERSION NT94510J.15A.0065.2005.1103.1803

I'll going to upgrade the bios.

Processor type: Intel (R) Pentium(R) D CPU 2.80GHz
Intel (R) EM64T Capable.

Using 512MB of DDR2 Dual Channel, 
ASL0 256MB
ASL1 Not Installed
BSL0 256MB
