[coreboot] mtrr: your BIOS has set up an incorrect mask

[Andreas B. Mundt]

Hi,

today, after quite some time running coreboot on my machine
(GA-M57SLI-S4), I updated coreboot to the latest revision, 5908.

Now, my system complains about "mtrr: your BIOS has set up an
incorrect mask, fixing it up." and I get a kernel oops. (See attached dmesg).

I looked in my old syslogs, and there I already find "mtrr: type mismatch for
e0000000,10000000 old: write-back new: write-combining", but no kernel
oops.

I have only very limited time to follow up on this, but if there's an
easy fix, it would be great.

Regards,
    Andi
