Thanks for this patch. I was having the exact same symptoms as Justin Piszcz,
on a different, but similar motherboard:
Motherboard: GigaByte GA-G33-DS3R
BIOS rev: F2
Chipset: Intel G33
Distro: Fedora 7 x86_64
Building vanilla 2.6.22-rc4 with your patch solved the problem.
I'm now seeing this in the syslog
**** WARNING: likely BIOS bug
**** MTRRs don't cover all of memory, trimmed 196608 pages
leaving me 7416672 kB of usable memory.
If there's any way I can help with more info or testing,
then let me know.
That's strange, I guess different chipsets 'chew' up different amounts of
memory OR you have your DVT(?) (video-card memory/aperature) set to 256MB?
I have mine set to 128MB, in top:
Mem: 8039576k total, 6187304k used, 1852272k free, 696k buffers
What type of memory are you using and what is your DVT set to?
