Re: [PATCH] trim memory not covered by WB MTRRs

[Pim Zandbergen]

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
Memory: 8GB
Distro: Fedora 7 x86_64
Kernel: kernel-2.6.21-1.3194.fc7

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.

Thanks,
Pim
