This is not just a UDP issue. I've seen crashes and/or throughput drops running
TCP/IP uplink iperf3 traffic to test maximum bandwidth.

We have a system with several of the AX200 NICs in it, kernel is 5.2.14+. We ran a udp upload
test of 10Mbps across all radios, and after about 10 minutes one of the radios crashed and could

I will open a bug in the kernel bug tracker.
Hello Ben,
We observed similar issues in our tests as well. All the details
have been described in kernel bugzilla issue:
https://urldefense.proofpoint.com/v2/url?u=https-3A__bugzilla.kernel.org_show-5Fbug.cgi-3Fid-3D205061&d=DwIFAg&c=MHZppzMdXMt3JYjCV71UsQ&r=RFH8dgrFzz0_hnNXpEl_u3TZqD-B6kYLzfvbDuCKw3U&m=opeh64GEVevn0071vriL-kH2B_orc25yacBPa3YdgLI&s=CKuyBZ0VdAQocDiZGOIDyDC6GG9w4E7OikmGvzblazU&e=
Thanks for the reports!
Ben also added a bug in bugzilla[1], let's use that one for tracking
(I'll mark Sergey's as a duplicate).
This is a know issue and our PHY team is already working on it
internally. I don't have much more details at the moment, but I'll
update the bugzilla entry as soon as we know more.
