Proxmox 2.2/2.1 16 GB RAM on Intel MTRR problem

[yegor]

Hello, people.

I had A proxmox 2.2. upgraded a RAM from 4 (2*2GB) to 16 (2*8GB)
after that I had a "*bad*gran_size:" in the kernel.log

and when i want to start VM (Windows) on the step of graphic booting Proxmox is gonig to reboot

I fixed grub, adding a string "enable_mtrr_cleanup mtrr_spare_reg_nr=1 mtrr_gran_size=32M mtrr_chunk_size=128M"
after that i had these strings in log file :
[kernel] mtrr: no more MTRRs available
[kernel] [drm] MTRR allocation failed. Graphics performance may suffer.

after that i tried to instal mtrr-uncover, but it shows error...

videocard is onboard...

my video card memory is in base=0x0d0000000 of MTRR and has a size=0x40000000 (256 M)

when I plug in 2*8GB /proc/mtrr shows

reg00: base=0x000000000 ( 0MB), size=16384MB, count=1: write-back
reg01: base=0x400000000 (16384MB), size= 1024MB, count=1: write-back

reg07: base=0x430000000 (17152MB), size= 256MB, count=1: uncachable

when return to 2*2GB

reg06: base=0x0d0000000 ( 3328MB), size= 256MB, count=1: write-combining

i tried to clean up whole file /proc/mtrrmc and remapp memory regarding on 16 GB RAM minus 256 M AGP like this

#!/bin/sh
