Created attachment 190571 [details] picture of garbled screen I tried to bisect this. but whenever i reach the i915 drm changes computer locks during boot which defeats the purpose (skipped many commits w/o success). Im attaching a dmesg of a booting kernel and a picture of the screen. a letterbox of garbled screen from about [0,10] to [1024,768] (aprox) is garbled. the rest of the screen works as it should. Trying to take a screenshot with the gnome-screenshot app produces a correct image including the area that is garbled. 00:02.1 Display controller [0380]: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller [8086:27a6] (rev 03) git bisect start # good: [64291f7db5bd8150a74ad2036f1037e6a0428df2] Linux 4.2 git bisect good 64291f7db5bd8150a74ad2036f1037e6a0428df2 # bad: [6ff33f3902c3b1c5d0db6b1e2c70b6d76fba357f] Linux 4.3-rc1 git bisect bad 6ff33f3902c3b1c5d0db6b1e2c70b6d76fba357f # good: [dd5cdb48edfd34401799056a9acf61078d773f90] Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next git bisect good dd5cdb48edfd34401799056a9acf61078d773f90 # bad: [f377ea88b862bf7151be96d276f4cb740f8e1c41] Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux git bisect bad f377ea88b862bf7151be96d276f4cb740f8e1c41 # good: [abebcdfb64f1b39eeeb14282d9cd4aad1ed86f8d] Merge tag 'sound-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound git bisect good abebcdfb64f1b39eeeb14282d9cd4aad1ed86f8d # bad: [bef2c7bd578e91c9c10983e0c15c4501127b77ca] Merge tag 'drm/tegra/for-4.3-rc1' of git://anongit.freedesktop.org/tegra/linux into drm-next git bisect bad bef2c7bd578e91c9c10983e0c15c4501127b77ca # bad: [97d3308ab245c51ae237b3444afa7ae87aa9bcd4] drm/i915: Add HAS_CORE_RING_FREQ macro git bisect bad 97d3308ab245c51ae237b3444afa7ae87aa9bcd4 # skip: [75289874e4484cd4702b3341b654b45b4a09b9d3] drm/i915: Update add_request() to take a request structure git bisect skip 75289874e4484cd4702b3341b654b45b4a09b9d3 # skip: [e62925567c7926e78bc8ca976cde5c28ea265a49] drm/i915/bxt: BUNs related to port PLL git bisect skip e62925567c7926e78bc8ca976cde5c28ea265a49 # skip: [76c3916887f1225db4b4960c59820db1a995f3cb] drm/i915: Update deferred context creation to do explicit request management git bisect skip 76c3916887f1225db4b4960c59820db1a995f3cb # skip: [2e906beac6be0116c557f96d1c07cb7a955f8059] drm/i915/gtt: Reorder page alloc/free/init functions git bisect skip 2e906beac6be0116c557f96d1c07cb7a955f8059
