This is also failing with focal/linux on the node dryden.

The latest result is from 5.4.0-85.95, which is stopping around this test:

04:57:26 DEBUG| [stdout] # selftests: net: reuseport_bpf_cpu
[...]
04:57:26 DEBUG| [stdout] # ---- IPv6 UDP ----

04:57:26 DEBUG| [stdout] # send cpu 151, receive socket 151
04:57:26 DEBUG| [stdout] # ---- IPv4 TCP ----

This is from an automated test run, so I don't have access to the kernel logs.

I have found the issue on all the regression tests run on this system since the oldest results we still have (5.4.0-76.85).
