Hi, I do not believe canonical is committing to fix all the
upstream/mainline selftest failures. However, if there are additional
selftest regressions with the ubuntu kernel which are not seen with the
mainline build, those are worth looking into. If these selftests never
pass on POWER maybe it is worth pinging power kernel maintainers to mark
these as expected failures? Regards, Dimitri.
