Our test team reported this problem. The hardware is Intel x86-64 with pcie to m.2 adapter boards and 8 total AX200 radios in one system. Notes on the AX crashes: - When the crash happens, the station does not seem to make a full recovery. There are many duplicate rx packets on the UDP download side. The upload direction is normal with no duplicate packets. - Traffic is fixed after resetting the station. - Sometimes traffic just stops completely for both sides and cannot resume until resetting the station. - I've found a way to reproduce a crash fairly reliably. Just in case it's a different crash, I'm uploading a separate crash file. It'll have wiphy0 in the file name. - To reproduce the crash, I ran UDP upload traffic at 100 Mbps on one radio (wiphy1). Then I brought up a second station on another radio (wiphy0). The station on wiphy0 will then crash as it comes up. If there is no traffic flowing on the wiphy1 radio, or if it is only doing 30Mbps upload, the station doesn't crash. - Traffic is over the air and not encrypted. I'm using our LANforge virtual AP on channel 36. - I was also able to get a crash with an Asus AX6000 AP. My earlier method of reproducing the crash did not work. Basically I got it to crash running 160 Mbps UDP upload on one AX station then resetting 7 other stations (each on their own AX radio).
