Hi, Patricia. Can you clarify if you always need to run the hotplug test before reuseport_bpf_cpu in order to reproduce? I wonder what is the state that the hotplug test leaves the system in? How is it being run? The makefile runs it with the -a option, which in the systems I have available would fail to offline the last CPU (which is expected, different behavior from x86, where cpu0 cannot be offlined). Running it without any options would only offline the last CPU and online it again.
I tried looking for differences between our kernels and 5.11.22 and the only cpuset changes I noticed were already present in the kernel you have just tested, and they were on paths unrelated to hotplug or BPF, so I am still baffled as to the real differences here. And given the different systems fail differently, it looks like this will require a dump or xmon so we can debug it. Thanks for all the help. I may ask for system access next week in order to help there.
