Hi all, I get messages about overlapping. This is not only gentoo-sources, but 2.6.14 kernels in general. Updating to 2.6.14-r2 didn't fix it. Previous kernel didn't have this issue. I get these messages: mtrr: 0xd0000000,0x10000000 overlaps existing 0xd0000000,0x8000000 mtrr: 0xd0000000,0x10000000 overlaps existing 0xd0000000,0x8000000 mtrr: 0xd0000000,0x10000000 overlaps existing 0xd0000000,0x8000000 In addition /proc/mtrr is different. 2.6.13-gentoo-r5: reg00: base=0x00000000 ( 0MB), size= 512MB: write-back, count=1 reg01: base=0xe0000000 (3584MB), size= 32MB: write-combining, count=2 reg02: base=0xd0000000 (3328MB), size= 128MB: write-combining, count=3 2.6.14-gentoo-r2: reg00: base=0x00000000 ( 0MB), size= 512MB: write-back, count=1 reg01: base=0xe0000000 (3584MB), size= 32MB: write-combining, count=2 reg02: base=0xd0000000 (3328MB), size= 128MB: write-combining, count=2 I haven't found any side effects yet. But something is just wrong. I don't think it's my hardware. But anyway.

I just found out that the overlap messages are issued when X starts. Before that everything seems ok (no errors/warnings). Before X is started /proc/mtrr looks like this: reg00: base=0x00000000 ( 0MB), size= 512MB: write-back, count=1 reg01: base=0xe0000000 (3584MB), size= 32MB: write-combining, count=2 reg02: base=0xd0000000 (3328MB), size= 128MB: write-combining, count=1
In future, please use the attachment feature to post large files. Is this reproducible on the latest development kernel? (currently vanilla-sources-2.6.15_rc2)
Hi Daniel! Okidoki, will do. I tried 2.6.15_rc2 and it's still there. mtrr: 0xd0000000,0x10000000 overlaps existing 0xd0000000,0x8000000 mtrr: 0xd0000000,0x10000000 overlaps existing 0xd0000000,0x8000000 mtrr: 0xd0000000,0x10000000 overlaps existing 0xd0000000,0x8000000
Please add your experiences to http://bugzilla.kernel.org/show_bug.cgi?id=5319
Sebastian, is this still an issue with the latest kernel (2.6.21 or newer)?
Hello Daniel, thanks for the reminder. No, the problem has been solved in 2.6.20. All's good now (again). Please close. Regards Sebastian
Ok, thanks for the update
