It may or may not be related but on MikroTik RB951Ui-2HnD (AR9340 Rev:3)

- OpenWrt 23.05 (kernel 5.15.137, backports 6.1.24): works fine
- OpenWrt 24.10.3 (kernel 6.6.104, backports 6.12.44): crashes at 
  module load

I haven't tested on 24.10.8 or 25.x.

dmesg on 24.10.3:
  ath: phy0: request GPIO11 failed:-517
  WARNING: CPU: 0 PID: 626 at hw.c:2920 [ath9k]

GPIO11 is the WLAN LED on this board. It seems the GPIO controller isn't ready when ath9k probes.

Workaround I found was adding a sysfs LED entry (sysfs='ath9k-phy0') in /etc/config/system and it makes the crash disappear. Although the LED doesn't light up.

Without the LED entry it goes into a crash loop (CPU load 7+ on single-core MIPS).
