Version: 20260916-1

Hi Ben,

thanks for the pointer. 20260916-1 fixes it.

Tested on the same machine and kernel (7.2.7.1), package installed from
sid, no files replaced:
- pm_test=devices: "amdgpu 0000:07:00.0: SMU is resumed successfully!"
- real s2idle, 30 s via rtcwake: clean resume, amd_pmc reports "Last
S0i3 Status: Success",
  42 ms to S0i3, 22.7 s in S0i3, 0.54 s resume. No ALIB/SMU timeouts.

Loaded firmware versions (amdgpu_firmware_info), in case it helps to
narrow down the culprit:

                 20260810-1 (broken)   20260916-1 (works)   linux-
firmware 20240318 (works)
  DMCUB          0x05003300            0x05003500           0x05001c00
  PSP ASD        0x21000115            0x21000118           0x210000c7
  TA HDCP / DTM  0x17000052/1200001e   0x17000053/1200001f 
0x1700003c/12000016
  VCN            0x04121015            0x0412100f           0x0311e004
  GC RLC         0x20                  0x1f                 0x1f
  GC MEC / PFP   0x1c / 0x12           0x1c / 0x12          0x14 / 0x0e
  SMU (BIOS)     98.26.0               98.26.0              98.26.0

So MEC/PFP are not involved; the regression in 20260810 is in DMCUB,
the PSP TA, VCN or RLC. Given the
"Revert updates to VCN firmware in 20260810" entry (#1148284), VCN
looks like the likely one. I have not
bisected the single blob.

From my side this bug can be closed as fixed in 20260916-1.

Regards,
Daniel
