After pulling iwlwifi-fixes-for-kvalo-2019-07-30, I still get firmware
crashes on my "Intel(R) Dual Band Wireless AC 8260" which uses firmware
version 36. I tried the latest ucode in linux-firmware (36.77d01142.0),
but it seems GEO_TX_POWER_LIMIT is not yet implemented there.

Could you let me know which firmware version I need for Linux 5.3? Can
there be a check in iwl_mvm_sar_geo_support() that the backported
support is indeed available?

Thanks,
Jonas
