Intel 8265 Firmware issue with TPC (802.11h)

Hi All,

Network Engineering of medical company reported Intel 8265 chipset crashing while doing TPC whenever asked to connect to any DFS channel. Tests were done with Linux machine, driver/kernel version- 4.9 and 4.8. FW in the chipset is 22.361476.0

The "dmesg" shows following error messages:

Iwlwifi 0000:02:00.0: Queue 2 stuck for 10000ms

….

Iwlwifi 0000:02:00.0: Microcode SW error detected. Restarting 0x2000000

Ieee80211 phy0: Hardware restart was requested

….

Complete logs are attached.

We would like to know why this issue occurs and are there other conditions which can cause such crashing.

Thanks
