[Kernel-packages] [Bug 930007] Re: When booting with 32GB ram linux fails to find optimal mtrr when i915 (HD 3000) has 512 MB Ram
Hi, I'm seeing this on a i7 server with 32Gs of RAM as well. It runs raring. Should I post any info on this bug or do you want a separate bug ? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/930007 Title: When booting with 32GB ram linux fails to find optimal mtrr when i915 (HD 3000) has 512 MB Ram Status in The Linux Kernel: Confirmed Status in “linux” package in Ubuntu: Incomplete Bug description: I have an ASUS P8Z68-V PRO, W/ BIOS 1101, 32GB of RAM and I am running Ubuntu precise 12.04.

GNAServicesInc, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, could you please run the following command in the development release from a Terminal (Applications-Accessories-Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux replace-with-bug-number Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.11-rc5 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.
