https://bugzilla.kernel.org/show_bug.cgi?id=206519 --- Comment #6 from Shlomo (shl...@fastmail.com) --- Yes, this fixes the bug. I applied your patch over linux v5.5, but I first had to modify it so it would apply: - drm_connector_attach_content_protection_property(>base, true); + drm_connector_attach_content_protection_property(>base, false); -- You are receiving this mail because: You are watching the assignee of the bug. ___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

https://bugzilla.kernel.org/show_bug.cgi?id=206519 --- Comment #4 from Shlomo (shl...@fastmail.com) --- I bisected the bug. The first bad commit is 96a3b32e67236f547cc8acd69d5a3cef125b2295 (drm/amd/display: only enable HDCP for DCN+) with ea268870d6f548d0661e896e9746673210c1fa79 (drm/amd/display: Add hdcp to Kconfig) cherry-picked on top of it. (The previous commit da3fd7ac0bcf372cc57117bdfcd725cca7ef975a with ea268870d6f548d0661e896e9746673210c1fa79 cherry-picked on top of it is good.) The call trace for this bug is the same as I posted above. -- You are receiving this mail because: You are watching the assignee of the bug. ___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

[Bug 206519] [amdgpu] kernel NULL pointer dereference on shutdown
https://bugzilla.kernel.org/show_bug.cgi?id=206519 --- Comment #3 from Shlomo (shl...@fastmail.com) --- The bug first occurs in Arch Linux 5.5.arch1-1, which set CONFIG_DRM_AMD_DC_HDCP=y [1]. Arch Linux 5.4.15.arch1-1 is good. Arch Linux 5.4.15.arch1-1 with CONFIG_DRM_AMD_DC_HDCP=y set (and no other changes) is bad. Arch Linux 5.5.arch1-1 (and later) is bad. (CONFIG_DRM_AMD_DC_HDCP=y is set) Testing the most recent Arch Linux kernel shows the same: Arch Linux 5.5.3.arch1 is bad. Arch Linux 5.5.3.arch1 with CONFIG_DRM_AMD_DC_HDCP unset is good. This means that this bug was triggered by changes to the config, not kernel changes, so I don't know if this is a regression or not.
