I'm running 64-bit Gentoo on an Intel 4-core i3 with an Intel integrated |
2 |
graphics controller. An excerpt from dmesg follows, with the video- |
3 |
related stuff. Note the two lines that I've split off. They mention |
4 |
the mtrr type mismatch and the allocation failure. Is this a problem |
5 |
and if so, what do I do about it? |
