Public bug reported: Binary package hint: linux-image-2.6.28-11-generic
- Kubuntu Jaunty 9.04 - Acer Aspire One I report exactly the same as reported here: http://www.linux-archive.org/debian-kernel/283649-bug-524274-linux-image-2-6-29-1-686-enable_mtrr_cleanup-does-not-clean-up-mtrrs.html I'm trying to tunne my Acer Aspire One by following the Ubuntu documentation: https://help.ubuntu.com/community/AspireOne As very well explained here: http://perens.com/blog/2009/01/31/13/ Acer Aspire One configures itself to use all 8 of the available MTRRs: ~# cat /proc/mtrr reg00: base=0x0fffe0000 ( 4095MB), size= 128KB, count=1: write-protect reg01: base=0x0fffc0000 ( 4095MB), size= 128KB, count=1: uncachable reg02: base=0x000000000 ( 0MB), size= 512MB, count=1: write-back reg03: base=0x020000000 ( 512MB), size= 512MB, count=1: write-back reg04: base=0x03f800000 ( 1016MB), size= 8MB, count=1: uncachable reg05: base=0x03f600000 ( 1014MB), size= 2MB, count=1: uncachable reg06: base=0x03f500000 ( 1013MB), size= 1MB, count=1: uncachable reg07: base=0x000000000 ( 0MB), size= 128KB, count=1: uncachable I've added "enable_mtrr_cleaup" to GRUB menu.list file. And this is what syslog says (related to "mtrr" after restarting): ---------------------------------- Apr 30 00:06:19 portatil kernel: [ 4068.077232] [drm:i915_get_vblank_counter] *ERROR* trying to get vblank count for disabled pipe 0 Apr 30 00:06:19 portatil kernel: [ 4068.079899] mtrr: no MTRR for 40000000,10000000 found Apr 30 00:06:57 portatil kernel: [ 0.000000] Kernel command line: root=UUID=076a4c4b-7ae4-4375-9e13-6ab1c3ed8de9 ro enable_mtrr_cleaup quiet splash Kernel command line: root=UUID=076a4c4b-7ae4-4375-9e13-6ab1c3ed8de9 ro enable_mtrr_cleaup quiet splash ---------------------------------- Also, /proc/mtrr remains the same (8 entries). But the fact is that I don't know how /proc/mtrr should look after "enable_mtrr_cleanup" kernel option is enabled.
