Attachment-A

My PowerColor Radeon Rx 6400 ITX never works. I explain it step by step.


My regular hardware set is here and it surely works well,

CPU: Ryzen 3 PRO 4350G
MB: Asrock A520M-ITX/AC 
BIOS: v1.90
Display output: From Ryzen 3 PRO 4350G via HDMI.

Next, I turn off the power supply and add Radeon RX 6400 and output from RX
6400.
In this time, a mosaic screen is shown. After some seconds, the screen becomes
black out.
Neither CTRL-ALT-DEL nor SysRq keys are work. (Attachment-A is the journal of
this run)

Next, I add the Rx 6400 and change display output via Ryzen 3 PRO 4350G. The
run goes to reboot automatically. The journal is Attachment-B.

Finally, the run after the automatic reboot works. The journal is attachment-C.

I put RX 6400 and output from RX 6400. It crashed and I could not do soft
reset. Thus, I turned off the power supply.

Next, I change my output from RX 6400 to Ryzen 4350G. It frozen after boot. I
could not do soft reset. Thus, I turned off the power supply.

journal with 4350G and amdgpu.runpm=0, 2nd boot.

Next, I kept the hardware setting (RX 6400 was still on but output from Ryzen
4350G) and boot. This is the journal.

Adding amdgpu.aspm=0 makes my Rx 6400 work fine.
Thank you.
