https://bugzilla.kernel.org/show_bug.cgi?id=201273 Marco (rodomar705@xxxxxxxxxxxxxx) changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |rodomar705@xxxxxxxxxxxxxx --- Comment #48 from Marco (rodomar705@xxxxxxxxxxxxxx) --- Same here on a B450 and a RX580 GPU. Random black screen with complete lockup of the system (panic, probably?) sometimes after booting up the system, beetween 5 seconds and two minutes post graphical boot. If the system survives this time it's stable until shutdown. Quite annoying, frankly. I still need to test properly the module parameter amdgpu.dc=0, that seems to disable the firmware load of the Display Controller (if I remember correctly); but what feature of the card (if any at all) will not work if the firmware is not loaded? Monitor used is a 120 Hz connected via DVI-D to the GPU. Since someone quoted that was simply a lockup of the output, simply fixed with a replug of the monitor, I've tried to connect the monitor via HDMI after it froze and blackscreened; however no output there either, and no response from the system when I was pressing the power button; henceforth that to me look like a kernel panic. It is a problem of the open source driver or the DC firmware itself the cause of this panics? Has anyone tried to contact AMD about this issue if it's the latter one? -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
