I didn't verify whether resume works on Windows > though. IIRC the issue is that ath11k expects the firmware to be running during suspend. And this was because shutting down the firmware for suspend caused problems in the MHI subsystem during resume. To fix this I suspect we need changes both in ath11k and in the MHI subsystem, so not easy. --=20 https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatc= hes
