Bisection points to git-x86.patch, though. git-bisect start # good: [f05092637dc0d9a3f2249c9b283b973e6e96b7d2] Linux 2.6.24-rc3 git-bisect good f05092637dc0d9a3f2249c9b283b973e6e96b7d2 # bad: [46c8c396d2c87b786a7fac615c289f85a18e53ce] w1-build-fix git-bisect bad 46c8c396d2c87b786a7fac615c289f85a18e53ce # bad: [4e22f4852c48e1eddfe04299e78c0456164abe86] frv-move-dma-macros-to-scatterlisth-for-consistency git-bisect bad 4e22f4852c48e1eddfe04299e78c0456164abe86 # bad: [4e22f4852c48e1eddfe04299e78c0456164abe86] frv-move-dma-macros-to-scatterlisth-for-consistency git-bisect bad 4e22f4852c48e1eddfe04299e78c0456164abe86 # good: [d5135f31313af2be37d8ccb71e2a42f8e221d8c4] ide-mm-ide-disk-extend-timeout-for-pio-out-commands git-bisect good d5135f31313af2be37d8ccb71e2a42f8e221d8c4 # good: [6be815e83f506f4c39a46cf59014e29a95c5e6c4] iommu-sg-merging-call-blk_queue_segment_boundary-in-__scsi_alloc_queue git-bisect good 6be815e83f506f4c39a46cf59014e29a95c5e6c4 # good: [6be815e83f506f4c39a46cf59014e29a95c5e6c4] iommu-sg-merging-call-blk_queue_segment_boundary-in-__scsi_alloc_queue git-bisect good 6be815e83f506f4c39a46cf59014e29a95c5e6c4 # bad: [c792db6d06114a85e33a27c89e9e979f11b951c4] slub-fix-coding-style-violations git-bisect bad c792db6d06114a85e33a27c89e9e979f11b951c4 # bad: [c792db6d06114a85e33a27c89e9e979f11b951c4] slub-fix-coding-style-violations git-bisect bad c792db6d06114a85e33a27c89e9e979f11b951c4 # bad: [76f3939b76ff557f73720b57a16716196f04e407] x86_64-make-sparsemem-vmemmap-the-default-memory-model-v2 git-bisect bad 76f3939b76ff557f73720b57a16716196f04e407 # good: [b8ba611566d8799a979b190d4bb14305ca64ee0e] sis-fb-driver-_ioctl32_conversion-functions-do-not-exist-in-recent-kernels git-bisect good b8ba611566d8799a979b190d4bb14305ca64ee0e # good: [e34995928859308d2abef1709332e2b12d36db2f] git-ipwireless_cs git-bisect good e34995928859308d2abef1709332e2b12d36db2f # bad: [f520abbbe11bc8253714bcd34aaaf19bdf82189e] git-x86-identify_cpu-fix git-bisect bad f520abbbe11bc8253714bcd34aaaf19bdf82189e I honestly tried fresh #mm from x86 tree -- the one which ends at commit 70be766db1105c0fc9aed8e954d0c343c1eda067 "x86: Add the RDC machine specific reboot fixup". FWIW, commit "x86: validate against ACPI motherboard resources" is innocent. After "x86: make stack size configurable" damn thing wouldn't build and applying fixets from -mm doesn't help at 3AM.
