I expected an instant lock up when insmodding the modules however that
didn't happen
Please also find the dmesg attached

Hi Mike,
To grab console output, you could also try to blacklist amdgpu at
startup and load it later.
Can you provide your acpidump (and lspci -nn, especially if you do not
have a dmesg).
This is the call chain:
+ amdgpu_atpx_detect
+ amdgpu_atpx_pci_probe_handle
+ return if ATPX ACPI handle cannot be found
+ set amdgpu_atpx_priv.bridge_pm_usable
+ amdgpu_atpx_init
+ amdgpu_atpx_validate
+ use amdgpu_atpx_priv.bridge_pm_usable
I wonder whether newer devices remove ATPX completely. If that is the
case (please provide acpidump!), can you try this hack:
diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_atpx_handler.c
b/drivers/gpu/drm/amd/amdgpu/amdgpu_atpx_handler.c
index 951addf..5c23382 100644
--- a/drivers/gpu/drm/amd/amdgpu/amdgpu_atpx_handler.c
+++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_atpx_handler.c
@@ -487,6 +487,7 @@ static bool amdgpu_atpx_pci_probe_handle(struct pci_dev
*pdev)
status = acpi_get_handle(dhandle, "ATPX", &atpx_handle);
if (ACPI_FAILURE(status)) {
amdgpu_atpx_priv.other_handle = dhandle;
+ amdgpu_atpx_priv.bridge_pm_usable = true;
return false;
}
amdgpu_atpx_priv.dhandle = dhandle;
This is not intended for merging, but just testing a hypothesis.
Kind regards,
Peter
