Thank you for this wiki page, and all the work with the CI infrastructure!

For the debug options, I see that you are using:

  kernel/configs/x86_debug.config

It looks like this is specific for the 'tip' tree:

  Debugging options for tip tree testing

I don't know if it is still maintained, e.g. it includes DEBUG_SLAB
option. But also, it enables options that are maybe not needed: GCOV?
X86_DEBUG_FPU?
Maybe it is better not to use this .config file, no?

For our CI validating MPTCP tests in a "debug" mode, we use
"debug.config" without "x86_debug.config". On top of that, we also
disable "SLUB_DEBUG_ON", because the impact on the perf is too
important, especially with slow environments. We think it is not worth
it for our case. You don't have the same hardware, but if you have perf
issues, don't hesitate to do the same ;)

Linked to the discussion we had last week, I can describe which patches
are being tested if you think it can help others :)

Cheers,
