[Regression] AMDGPU (AMD RX 640) fails to display after upgrading to kernel 5.14 and later

I have an AMD RX 640 VGA card and it was working fine on kernel 5.13. But it fails to display after I upgrade the kernel to 5.14 or even latest version. The dmesg shows as follows.

The problem can be fixed by disabling ASPM or with my customized kernel with commit 0064b0ce85bb ("drm/amd/pm: enable ASPM by default") reverted. However, the display seems to respond very slow with keyboard/mouse input. Please help verify the ASPM problem on this and let me know if I have to provide any further information. Thanks
