Description Carsten Hatger 2023-01-23 18:24:53 UTC

Created attachment 303638 [details]
hibernation log as provided by systemd's journal

On system HP Pro x360 435 G9 w/ 
- AMD 5825U and 
- Qualcomm Fast Connect 6900 Wi-Fi 6E 802.11ax

kernel module ath11k_pci fails to resume from hibernation. 

Kernel rev. is:
 v6.1.7 vanilla

Firmware rev. is:
 - WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.9

IMHO this is not a regression of https://lore.kernel.org/lkml/20211208094035.GF70121@thinkpad/T/ since the error occurs despite the resume being forced by 

- mhi_pm_resume_force in drivers/net/wireless/ath/ath11k/mhi.c

BTW: There are no issues when suspending to any of the s0ix states.

Current workaround is to bring the radio down and remove the module before hibernating. Resume works the same by reversing these actions.

Please let me know if I can further assist in resolving this issue.

Yours,
Carsten
