Since commita481daa88f("drm/radeon: always apply pci shutdown callbacks"), a Dell Latitude D600 laptop has crashed on shutdown. The PCI Identification of the graphics adapter is "VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] RV250/M9 GL [Mobility FireGL 9000/Radeon 9000] [1002:4c66] (rev 01)". Prior to commitb0c80bd5d2("drm/radeon: fix up dp aux tear down (v2)"), I have no idea where the panic happened as the screen was blanked before the crash. Since that more recent change, the panic has been in routine radeon_connector_unregister(), and has been shown to be due to a NULL value in the ddc_bus member of struct drm_connector. Bug: https://bugzilla.kernel.org/show_bug.cgi?id=178421 Fixes:a481daa88f("drm/radeon: always apply pci shutdown callbacks") Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Cc: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
