1 Hi,

3 i'm not an expert on this subject myself but i found it nonetheless
4 interesting, here's what i found mostly by grepping and googling:

6 Here's someone who is also getting these huge reported memory sizes:
7 http://lkml.org/lkml/2005/9/12/35
8 Found it by googling for 983552MB, there's more there.

10 There's is some info on mtrr's with vesafb here:
11 /usr/src/linux-2.6.13-gentoo-r3/Documentation/fb/vesafb.txt, line 176
12 Seems to suggest trying video=vesafb:nomtrr if you're using vesafb.

14 Also some other reports seem to hint at Xorg as the culprit:
15 https://bugs.freedesktop.org/show_bug.cgi?id=4310
16 and others found by googling "mtrr: type mismatch for".
17
18 You might want to also grep Xorg.log for the addresses provided by
19 'cat /proc/mtrr' or just the prefix such as
20 'grep -in 0xd /var/log/Xorg.0.log' in my case, that should some results
21 (Xorg.log doesn't seem to mention mtrr literally, as far as i can see).
22
23 I'm sorry that I don't have an answer to the actual problem, but I'm
24 very thankful for the interesting explanations about mtrr from both of
25 you (Duncan and Mark).

27 Cheers,
28 Marco
