The CI check is right: I generated the recipient list with git history disabled, so the blamed authors were omitted. The patches themselves are unchanged and are in the archive: https://lore.kernel.org/linux-wireless/20261002231013.11792-1-abdurrahmankaradag19@gmail.com/ Patch 1 is the one that touches lines you wrote: for a queue stopped by the PCI TX ring-full path, the stop reason is released only from the completion loop in rtw_pci_tx_isr(). Resetting the rings drops the descriptors whose completion would have carried that wake, so ieee80211_restart_hw() cannot recover a device that had stopped a queue. It comes with a reproducer and an A/B measurement. Sorry for the extra mail.
