I also see this -22 error (see my logs in [1]), even when the firmware
reboots normally. Do you see anything after these messages?

The problem which reverting 7fef431be9c9 helps has these errors:

ath11k_pci 0000:06:00.0: qmi failed memory request, err = -110
ath11k_pci 0000:06:00.0: qmi failed to respond fw mem req:-110

But these do not look same. I have:
