[fixed in linux-firmware 20240130.5217b76b] ath11k/QCNFA765 breaks suspend on laptop with amdgpu errors "MES failed to response msg=14" / "failed to reg_write_reg_wait"

Description

My Thinkpad P14s always fails to suspend.

The suspend kinda starts (screen turns off), but then immediately resumes, and these errors show up in dmesg:

[   54.594789] [drm:mes_v11_0_submit_pkt_and_poll_completion.constprop.0 [amdgpu]] *ERROR* MES failed to response msg=14
[   54.595098] [drm:amdgpu_mes_reg_write_reg_wait [amdgpu]] *ERROR* failed to reg_write_reg_wait

Here's a color-highlighted dmesg, for readability & context:

Relationship to ath11k

Unloading ath11k fixes the issue: after I modprobe -r ath11k_pci ath11k , suspend & resume work as expected (suggested here)

  • 6.6 also affected (this laptop has always had the issue since I bought it)
  • linux-firmware 20240115.9b6d0b08-2
• Bug reports upstream / in other distros:
  • RedHat Bug 2262577 - kernel-6.7.4 broken suspend (QCNFA765 ath11k) is a similar bug. It's not identical, though. For me, suspend fails and immediately resumes, for them suspend causes a deadlock: "Suspend causes deadlock. Screen goes black but does not turn on. Keyboard lights are on. Caps Lock does not respond suggesting deadlock. Nothing is logged to journal."
  • RedHat bug also links to maybe an issue in linux-firmware: https://bugzilla.redhat.com/show_bug.cgi?id=2262577#c17
  • RedHat bug also links to DRM/AMD bug #3132 - Asus Zephyrus G14 GA402 - Suspend not working reliably since Kernel 6.6.8

Steps to reproduce

1. Suspend, using the GNOME Shell action
