Unfortunately, I think the whole swath of commits bisect wants to test are broken (as in, they panic before I get to see whether or not the VGA is working), because the commit from which most of the drm trees were based appears to be broken. Nevertheless, I've included the new bisect log (four new commits marked skip as opposed to last time). I've also included the boot log from a crashing kernel, in case someone recognizes how I can avoid this during bisection. Note that this crash is *not* a regression that exists in current mainline -- bisecting this issue was the first time I had ever seen it. (Aside: is there a way to run "git bisect skip" without causing a new working tree to be immediately checked out? When I'm going to be picking the next commit manually anyway, having git bisect checkout a new tree arbitrarily, potentially forcing a complete recompile (~30 minutes) when the commit I picked could have been incrementally compiled in ~1 minute is pretty annoying...) git bisect start 'drivers/gpu' # bad: [c16fa4f2ad19908a47c63d8fa436a1178438c7e7] Linux 3.3 git bisect bad c16fa4f2ad19908a47c63d8fa436a1178438c7e7 # good: [805a6af8dba5dfdd35ec35dc52ec0122400b2610] Linux 3.2 git bisect good 805a6af8dba5dfdd35ec35dc52ec0122400b2610 # skip: [5d56fe5fd794a98c4f446f8665fd06b82e93ff64] Merge branch 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-core-next git bisect skip 5d56fe5fd794a98c4f446f8665fd06b82e93ff64 # good: [dffc9ceb55695f121adc57dd1fde7304c3afe81e] gma500: kill virtual mapping support git bisect good dffc9ceb55695f121adc57dd1fde7304c3afe81e # skip: [5c2a5ce689c99037771a6c110374461781a6f042] drm: add missing exports for i810 driver. git bisect skip 5c2a5ce689c99037771a6c110374461781a6f042 # skip: [44517c44496062180a6376cc704b33129441ce60] drm/radeon/kms: Add an MSI quirk for Dell RS690 git bisect skip 44517c44496062180a6376cc704b33129441ce60 # --- The commits below this point are newly tested --- # skip: [f7b24c42da1a7bbb98145d27aa716d8af3cae2a6] drm/nouveau/ttm: fix crash as a result of a recent ttm change git bisect skip f7b24c42da1a7bbb98145d27aa716d8af3cae2a6 # skip: [0c101461e267850925218d6a6872c379f2498b16] drm/nv40/pm: parse fan pwm divisor from vbios tables git bisect skip 0c101461e267850925218d6a6872c379f2498b16 # skip: [06e4cd64174b48345cbd99179b780a2bf4f96ab6] drm/radeon/kms: don't use 0 bpc for adjusting hdmi clock git bisect skip 06e4cd64174b48345cbd99179b780a2bf4f96ab6 # skip: [1fbe6f625f69e48c4001051dc1431afc704acfaa] Merge tag 'v3.2-rc6' of /home/airlied/devel/kernel/linux-2.6 into drm-core-next git bisect skip 1fbe6f625f69e48c4001051dc1431afc704acfaa Linux version 3.2.0-rc6-bisect-00099-g1fbe6f6 (nick@artemis) (gcc version 4.5.3 (Gentoo 4.5.3-r2 p1.1, pie-0.4.7) ) #60 PREEMPT Sun Apr 22 12:04:36 EDT 2012 Command line: root=md:name=newroot console=ttyS0,115200n8 BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009fc00 (usable) BIOS-e820: 000000000009fc00 - 00000000000a0000 (reserved) BIOS-e820: 00000000000e4000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 000000007ffc0000 (usable) BIOS-e820: 000000007ffc0000 - 000000007ffd0000 (ACPI data) BIOS-e820: 000000007ffd0000 - 0000000080000000 (ACPI NVS) BIOS-e820: 00000000fec00000 - 00000000fec01000 (reserved) BIOS-e820: 00000000fee00000 - 00000000fee01000 (reserved) BIOS-e820: 00000000ff7c0000 - 0000000100000000 (reserved) NX (Execute Disable) protection: active DMI 2.3 present.
