Content-Type: text/plain; charset=ISO-8859-15; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 4975 Lines: 116 Hello, I've just bisected a problem with 3.6.4. I had to revert commit 54ce8ce298f382a06186cb4672ad6aa090b050b6 (1bbbbe779aabe1f0768c2bf8f8c0a5583679b54a in mainline), otherwise my box didn't boot. I can't provide any output, because I don't see if that commit is applied. ;) Here is the start of the dmesg with the memory map (with the above commit reverted): ------------- [ 0.000000] Initializing cgroup subsys cpuset [ 0.000000] Initializing cgroup subsys cpu [ 0.000000] Linux version 3.6.4-00001-gcccc924 (root@krabat.ahsoftware) (gcc version 4.7.2 20120921 (Red Hat 4.7.2-2) (GCC) ) #258 SMP Mon Oct 29 11:08:32 CET 2012 [ 0.000000] Command line: ro root=/dev/sdb2 rootfstype=ext4 enforcing=0 cgroup_disable=memory vga=0x346 video=vesafb:mtrr:3,ywrap radeon.modeset=0 [ 0.000000] KERNEL supported cpus: [ 0.000000] AMD AuthenticAMD [ 0.000000] e820: BIOS-provided physical RAM map: [ 0.000000] BIOS-e820: [mem 0x0000000000000000-0x000000000009e7ff] usable [ 0.000000] BIOS-e820: [mem 0x000000000009e800-0x000000000009ffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000000e0000-0x00000000000fffff] reserved [ 0.000000] BIOS-e820: [mem 0x0000000000100000-0x000000009d7cafff] usable [ 0.000000] BIOS-e820: [mem 0x000000009d7cb000-0x000000009dd6afff] reserved [ 0.000000] BIOS-e820: [mem 0x000000009dd6b000-0x000000009dd7afff] ACPI data [ 0.000000] BIOS-e820: [mem 0x000000009dd7b000-0x000000009e0e6fff] ACPI NVS [ 0.000000] BIOS-e820: [mem 0x000000009e0e7000-0x000000009e669fff] reserved [ 0.000000] BIOS-e820: [mem 0x000000009e66a000-0x000000009e66afff] usable [ 0.000000] BIOS-e820: [mem 0x000000009e66b000-0x000000009e870fff] ACPI NVS [ 0.000000] BIOS-e820: [mem 0x000000009e871000-0x000000009ec8ffff] usable [ 0.000000] BIOS-e820: [mem 0x000000009ec90000-0x000000009eff3fff] reserved [ 0.000000] BIOS-e820: [mem 0x000000009eff4000-0x000000009effffff] usable [ 0.000000] BIOS-e820: [mem 0x00000000fec00000-0x00000000fec00fff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000fec10000-0x00000000fec10fff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000fed00000-0x00000000fed00fff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000fed40000-0x00000000fed44fff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000fed80000-0x00000000fed8ffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000ff000000-0x00000000ffffffff] reserved [ 0.000000] BIOS-e820: [mem 0x0000000100001000-0x00000001beffffff] usable [ 0.000000] NX (Execute Disable) protection: active [ 0.000000] DMI 2.7 present.
