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 ----

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).

Bug description:
It looks like our P8 node "entei" tend to fail with the IPv6 TCP test
from reuseport_bpf_cpu in ubuntu_kernel_selftests/net on 5.8 kernels:
# send cpu 119, receive socket 119
# send cpu 121, receive socket 121
# send cpu 123, receive socket 123
# send cpu 125, receive socket 125
# send cpu 127, receive socket 127
# ---- IPv6 TCP ----

It failed silently here, this can be 100% reproduced with Groovy 5.8
and Focal 5.8.
This will cause the ubuntu_kernel_selftests being interrupted, the
test result for other tests cannot be processed to our result page.
Please find attachment for the complete "net" test result on this node
with Groovy 5.8.0-52.59
Add the kqa-blocker tag as this might needs to be manually verified.
