            Bug ID: 204959
           Summary: iwlwifi: AX200: TOF_RANGE_REQ command is called, crash
                    on firmware.
           Product: Backports project
           Version: unspecified
    Kernel Version: 5.1.0-050100-generic
          Hardware: Intel
                OS: Linux
              Tree: Mainline
            Status: NEW

        Regression: No

I tried to measurement ftm_request through iw 5.3 version.
ex) iw wlan0 measurement ftm_request config_file which include <mac address>
bw=80 cf=5240 cf1=5210 asap.

At that time, iwlwifi always go to crash status.
- iwlwifi : backport-iwlwifi 4.3
- firmware : iwlwifi-cc-a0-48.ucode (firmware-version: 48.4fa0041f.0)
- kernel: 5.1.0-050100-generic

I think that there is a problem
 -> iwlwifi 0000:01:00.0: FW error in SYNC CMD TOF_RANGE_REQ_CMD
I attached dmesg, syslog, iwl.dump files.

There is a dmesg:
