--- Comment #6 from Andrei ([email protected]) ---
I also checked 6.18.2, it still exhibits the issue. I went through minor
versions between 6.17.1 and 6.17.11, and found the version where the issue was
first introduced.

6.17.4 - works
6.17.5 - works
6.17.6 - does not work

One extra note:

I see the amdgpu line that I originally thought associated the problem, also
appears in the dmesg output for working kernel versions.

For example, 6.17.4 (working):

[    6.602684] amdgpu 0000:c3:00.0: amdgpu: [drm] DMUB HPD RX IRQ callback:
link_index=5
[    6.612716] amdgpu 0000:c3:00.0: amdgpu: [drm] DMUB HPD RX IRQ callback:
link_index=5
[    6.634430] amdgpu 0000:c3:00.0: amdgpu: [drm] DMUB HPD RX IRQ callback:
link_index=5
[    6.639137] amdgpu 0000:c3:00.0: amdgpu: [drm] DMUB HPD RX IRQ callback:
link_index=5

6.17.5 (working):

[    6.468886] amdgpu 0000:c3:00.0: amdgpu: [drm] DMUB HPD RX IRQ callback:
link_index=5
[    6.473641] amdgpu 0000:c3:00.0: amdgpu: [drm] DMUB HPD RX IRQ callback:
link_index=5
[    6.479753] amdgpu 0000:c3:00.0: amdgpu: [drm] DMUB HPD RX IRQ callback:
link_index=5
[    6.492847] amdgpu 0000:c3:00.0: amdgpu: [drm] DMUB HPD RX IRQ callback:
link_index=5

The following may or may not be relevant, but here's something that appears
only in problematic versions, and is missing from working versions:

6.17.6:

[   18.911013] ath12k_pci 0000:c2:00.0: chan info: invalid frequency 6935 (idx
101 out of bounds)
[   18.986136] ath12k_pci 0000:c2:00.0: chan info: invalid frequency 7015 (idx

[   19.061037] ath12k_pci 0000:c2:00.0: chan info: invalid frequency 7095 (idx

[   20.562028] ath12k_pci 0000:c2:00.0: chan info: invalid frequency 6435 (idx

6.17.12:

[   34.459370] ath12k_pci 0000:c2:00.0: chan info: invalid frequency 6455 (idx
101 out of bounds)
[   34.534471] ath12k_pci 0000:c2:00.0: chan info: invalid frequency 6535 (idx

[   34.609497] ath12k_pci 0000:c2:00.0: chan info: invalid frequency 6615 (idx
101 out of bounds)
[   34.684571] ath12k_pci 0000:c2:00.0: chan info: invalid frequency 6695 (idx
101 out of bounds)

6.18.2:

[   14.236205] ath12k_pci 0000:c2:00.0: chan info: invalid frequency 5180 (idx
101 out of bounds)
[   14.391215] ath12k_pci 0000:c2:00.0: chan info: invalid frequency 5200 (idx
101 out of bounds)
[   14.546169] ath12k_pci 0000:c2:00.0: chan info: invalid frequency 5220 (idx

[   14.700826] ath12k_pci 0000:c2:00.0: chan info: invalid frequency 5240 (idx
101 out of bounds)

In working versions, ath12k_pci logging terminates with the following:

6.17.1:

[   38.914023] ath12k_pci 0000:c2:00.0: failed to enqueue rx buf: -28

6.17.4:

[   37.071153] ath12k_pci 0000:c2:00.0: failed to enqueue rx buf: -28

6.17.5:

[    6.586797] ath12k_pci 0000:c2:00.0: failed to enqueue rx buf: -28
