I haven't got a working kernel fresher than the fdaf9a5840ac commit on any machine (all machines have AMD graphics). Bisecting the kernel if we considered the mutex issue as "bad" state and all other non working state as "skip" did not lead to anything useful. Even if we consider "bad" all commits in which the kernel does not work, this also does not lead to anything good. Below I did it: $ git bisect log git bisect start # status: waiting for both good and bad commits # good: [fdaf9a5840acaab18694a19e0eb0aa51162eeeed] Merge tag 'folio-5.19' of git://git.infradead.org/users/willy/pagecache git bisect good fdaf9a5840acaab18694a19e0eb0aa51162eeeed # status: waiting for bad commit, 1 good commit known # bad: [babf0bb978e3c9fce6c4eba6b744c8754fd43d8e] Merge tag 'xfs-5.19-for-linus' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux git bisect bad babf0bb978e3c9fce6c4eba6b744c8754fd43d8e # 01 - good: [86c87bea6b42100c67418af690919c44de6ede6e] Merge tag 'devicetree-for-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux git bisect good 86c87bea6b42100c67418af690919c44de6ede6e # 02 - observed initial problem with mutex # bad: [43ab20c599f4dc4c3972a8386ef4ca3943b5f9cd] drm/i915/gt: Fix build error without CONFIG_PM git bisect bad 43ab20c599f4dc4c3972a8386ef4ca3943b5f9cd # 03 - observed invalid opcode: 0000 [#1] PREEMPT SMP NOPTI - RIP: 0010:free_pcp_prepare+0x58d/0x5a0 # bad: [790b45f1bc6736a8dd48ba5731b6871e0217311e] drm/i915/bios: Parse the seamless DRRS min refresh rate git bisect bad 790b45f1bc6736a8dd48ba5731b6871e0217311e # 04 - observed invalid opcode: 0000 [#1] PREEMPT SMP NOPTI - RIP: 0010:free_pcp_prepare+0x455/0x650 # bad: [c6ed9f66eb70aeaac9998bd3552ada740d90e20c] drm/nouveau/gr/gf100-: change gf108_gr_fwif from global to static git bisect bad c6ed9f66eb70aeaac9998bd3552ada740d90e20c # 05 good: [3123109284176b1532874591f7c81f3837bbdc17] Linux 5.18-rc1 git bisect good 3123109284176b1532874591f7c81f3837bbdc17 # 06 good: [711c7adc4687250deb550ee8a6994203f817b2ca] drm: exynos: dsi: Use drm panel_bridge API git bisect good 711c7adc4687250deb550ee8a6994203f817b2ca # 07 - observed invalid opcode: 0000 [#1] PREEMPT SMP NOPTI - RIP: 0010:free_pcp_prepare+0x35e/0x410 # bad: [047a1b877ed48098bed71fcfb1d4891e1b54441d] dma-buf & drm/amdgpu: remove dma_resv workaround git bisect bad 047a1b877ed48098bed71fcfb1d4891e1b54441d # 08 good: [644704740b8282c9ee9483a38666ee4a4561c37c] drm/amdgpu: use dma_resv_for_each_fence for CS workaround v2 git bisect good 644704740b8282c9ee9483a38666ee4a4561c37c # 09 - observed invalid opcode: 0000 [#1] PREEMPT SMP NOPTI - RIP: 0010:free_pcp_prepare+0x35e/0x410 # bad: [61fe0ab26e36998cebec48805d6873e31f0d79d7] drm/gma500: fix a missing break in psb_intel_crtc_mode_set git bisect bad 61fe0ab26e36998cebec48805d6873e31f0d79d7 # 10 good: [1c3b2a27def609473ed13b1cd668cb10deab49b4] drm/nouveau/clk: Fix an incorrect NULL check on list iterator git bisect good 1c3b2a27def609473ed13b1cd668cb10deab49b4 # 11 - observed invalid opcode: 0000 [#1] PREEMPT SMP NOPTI - RIP: 0010:free_pcp_prepare+0x35e/0x410 # bad: [aa46154355e1e81ef746470d2e88bdb283508bff] drm/ingenic: Add ingenic_drm_bridge_atomic_enable and disable git bisect bad aa46154355e1e81ef746470d2e88bdb283508bff # 12 good: [71d637823cac7748079a912e0373476c7cf6f985] dma-buf: finally make dma_resv_excl_fence private v2 git bisect good 71d637823cac7748079a912e0373476c7cf6f985 # 13 - observed invalid opcode: 0000 [#1] PREEMPT SMP NOPTI - RIP: 0010:free_pcp_prepare+0x35e/0x410 # bad: [33f2069fb6a9c2d6509accc39521d3f4d6369576] drm/nouveau: support more than one write fence in fenv50_wndw_prepare_fb git bisect bad 33f2069fb6a9c2d6509accc39521d3f4d6369576 # 14 - observed invalid opcode: 0000 [#1] PREEMPT SMP NOPTI - RIP: 0010:free_pcp_prepare+0x35e/0x410 # bad: [9cbbd694a58bdf24def2462276514c90cab7cf80] Merge drm/drm-next into drm-misc-next git bisect bad 9cbbd694a58bdf24def2462276514c90cab7cf80 # first bad commit: [9cbbd694a58bdf24def2462276514c90cab7cf80] Merge drm/drm-next into drm-misc-next Need an alternative way to find the problem.
