[iwlwifi] wpa_supplicant stuck in ieee80211_waitfor_parent on 15.1-RELEASE-p3

Hi,

I was referred here from the FreeBSD forum. On FreeBSD 15.1-RELEASE-p3, my Intel Wi-Fi connection repeatedly drops. When I run doas service netif restart, it hangs at:

Stopping wpa_supplicant.
Waiting for PIDS: 22482

Neither SIGTERM nor SIGKILL removes the process. ps shows:

PID PPID STAT WCHAN COMMAND
22482 1 Ds tq_drain /usr/sbin/wpa_supplicant -s -B -i wlan0 -c /etc/wpa_supplicant.conf -D bsd -P /var/run/wpa_supplicant/wlan0.pid

procstat -kk 22482 shows taskqueue_drain called from ieee80211_waitfor_parent, via ieee80211_ioctl and ifioctl.

The Wi-Fi adapter is detected as:

iwlwifi0@pci0:0:20:3: class=0x028000 rev=0x01 hdr=0x00 vendor=0x8086 device=0x51f1 subvendor=0x8086 subdevice=0x0094
vendor = 'Intel Corporation'
device = 'Raptor Lake PCH CNVi WiFi'
class = network

wlan0 has iwlwifi0 as its parent and currently reports status: no carrier. Before the hang, dmesg repeatedly reports linuxkpi_ieee80211_beacon_loss, “missed beacons exceeds threshold” and connection losses.

Is there a way to recover the driver and release the blocked taskqueue without rebooting? Is this a known issue on the 15.1 release branch? I can provide the complete command outputs if useful.

Regards
