So I don't think it can be qualified as a regression, but it is certainly rather annoying. Questions: - is it possible that the error occurs due to a kernel bug, or is this certain to be due to broken hardware? - as the error is non-fatal, should it maybe be changed from dev_err to dev_info, so that at least it does not show up during a boot with 'quiet'? - if broken hardware is common, should the kernel complain at all, or at least maybe show a slightly "friendlier" message?
