It is not clear to me how the patches you add on top of the ones from patchwork are managed. Then, I don't know if it can help, but on the debug instance, this command could be launched before starting the tests to double the timeout values in all the "net" selftests: $ find tools/testing/selftests/net -name settings -print0 | xargs -0 \ awk -i inplace -F '=' \ '{if ($1 == "timeout") { print $1 "=" $2*2 } else { print }}' > I wish the selftest subsystem had some basic guidance.
