> Matt, could you help enable verbose ath12k log to verify my guess?

Here are kernel logs with ath12k debugging enabled:
1. WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
   https://cmphys.com/ath12k/dmesg-6.12.35-ath12kdebug-fw0x100301e1-20250702.log
2. WLAN.HMT.1.1.c5-00284.1-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
   https://cmphys.com/ath12k/dmesg-6.12.35-ath12kdebug-fw0x1108811c-20250702.log

I captured these after setting CONFIG_ATH12K_DEBUG=y and running "echo
0xffffffff > /sys/module/ath12k/parameters/debug_mask" during boot
(using @reboot in crontab).
