Hmmm, no reaction since it was posted a while ago, unless I'm missing something. Huacai Chen, did you maybe miss this report? The problem is apparently caused by a commit of yours (that Javier applied), you hence should look into this. Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) -- Everything you wanna know about Linux kernel regression tracking: https://linux-regtracking.leemhuis.info/about/#tldr If I did something stupid, please tell me, as explained on that page. > git bisect start > # status: waiting for both good and bad commits > # good: [6995e2de6891c724bfeb2db33d7b87775f913ad1] Linux 6.4 > git bisect good 6995e2de6891c724bfeb2db33d7b87775f913ad1 > # status: waiting for bad commit, 1 good commit known > # bad: [2dde18cd1d8fac735875f2e4987f11817cc0bc2c] Linux 6.5 > git bisect bad 2dde18cd1d8fac735875f2e4987f11817cc0bc2c > # bad: [b775d6c5859affe00527cbe74263de05cfe6b9f9] Merge tag 'mips_6.5' > of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux > git bisect bad b775d6c5859affe00527cbe74263de05cfe6b9f9 > # good: [3a8a670eeeaa40d87bd38a587438952741980c18] Merge tag > 'net-next-6.5' of > git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next > git bisect good 3a8a670eeeaa40d87bd38a587438952741980c18 > # bad: [188d3f80fc6d8451ab5e570becd6a7b2d3033023] drm/amdgpu: vcn_4_0 > set instance 0 init sched score to 1 > git bisect bad 188d3f80fc6d8451ab5e570becd6a7b2d3033023 > # good: [12fb1ad70d65edc3405884792d044fa79df7244f] drm/amdkfd: update > process interrupt handling for debug events > git bisect good 12fb1ad70d65edc3405884792d044fa79df7244f > # bad: [9cc31938d4586f72eb8e0235ad9d9eb22496fcee] i915/perf: Drop the > aging_tail logic in perf OA > git bisect bad 9cc31938d4586f72eb8e0235ad9d9eb22496fcee > # bad: [51d86ee5e07ccef85af04ee9850b0baa107999b6] drm/msm: Switch to > fdinfo helper > git bisect bad 51d86ee5e07ccef85af04ee9850b0baa107999b6 > # good: [bfdede3a58ea970333d77a05144a7bcec13cf515] drm/rockchip: cdn-dp: > call drm_connector_update_edid_property() unconditionally > git bisect good bfdede3a58ea970333d77a05144a7bcec13cf515 > # good: [123ee07ba5b7123e0ce0e0f9d64938026c16a2ce] drm: sun4i_tcon: use > devm_clk_get_enabled in `sun4i_tcon_init_clocks` > git bisect good 123ee07ba5b7123e0ce0e0f9d64938026c16a2ce > # bad: [20d54e48d9c705091a025afff5839da2ea606f6b] fbdev: Rename > fb_mem*() helpers > git bisect bad 20d54e48d9c705091a025afff5839da2ea606f6b > # bad: [728cb3f061e2b3a002fd76d91c2449b1497b6640] gpu: drm: bridge: No > need to set device_driver owner > git bisect bad 728cb3f061e2b3a002fd76d91c2449b1497b6640 > # bad: [0f1cb4d777281ca3360dbc8959befc488e0c327e] drm/ssd130x: Fix > include guard name > git bisect bad 0f1cb4d777281ca3360dbc8959befc488e0c327e > # good: [0bd5bd65cd2e4d1335ea6c17cd2c8664decbc630] dt-bindings: display: > simple: Add BOE EV121WXM-N10-1850 panel > git bisect good 0bd5bd65cd2e4d1335ea6c17cd2c8664decbc630 > # bad: [60aebc9559492cea6a9625f514a8041717e3a2e4] drivers/firmware: Move > sysfb_init() from device_initcall to subsys_initcall_sync > git bisect bad 60aebc9559492cea6a9625f514a8041717e3a2e4 > # good: [8bb7c7bca5b70f3cd22d95b4d36029295c4274f6] drm/panel: > panel-simple: Add BOE EV121WXM-N10-1850 panel support > git bisect good 8bb7c7bca5b70f3cd22d95b4d36029295c4274f6 > # first bad commit: [60aebc9559492cea6a9625f514a8041717e3a2e4] > drivers/firmware: Move sysfb_init() from device_initcall to > subsys_initcall_sync
