So if I read it right, with an AP interface (ap_active stays set) the work now finds every per vif list empty and runs into this in __rtw_build_rsvd_page_from_vifs(): rsvd_pkt = list_first_entry_or_null(&rtwdev->rsvd_page_list, struct rtw_rsvd_page, build_list); if (!rsvd_pkt) { WARN(1, "Should not have an empty reserved page\n"); return -EINVAL; } Before this patch it built the page from the stale entries and did not warn. Maybe rtw_fw_update_beacon_work() could skip the download while RTW_FLAG_RESTARTING is set? The reconfig downloads the beacon again for BSS_CHANGED_BEACON anyway. Best regards, Luka Gejak
