14.2 dmesg
Starting from FreeBSD 14.3, the iwlwifi driver for Intel(R) Wi-Fi 6 AX101 fails
when running DHCP. The interface initially scans successfully, but once
dhclient starts, the driver encounters repeated errors.
Dmesg extract:
iwlwifi0: WRT: Collecting data: ini trigger 4 fired (delay=0ms).
iwlwifi0: Failed to send flush command (-5)
iwlwifi0: flush request fail

iwlwifi0: PHY ctxt cmd error. ret=-5
iwlwifi0: Scan failed! ret -5
iwlwifi0: ERROR: lkpi_ic_scan_start: hw_scan returned -5
The final line repeats indefinitely.
Full dmesg output for 14.2 and 14.3, as well as pciconf -lv, are attached for
reference.
Notes:
- The card can scan networks successfully before running DHCP.
- The issue does not occur on FreeBSD 14.2 using the same firmware.
- The firmware appears to load successfully in both versions.
