@Pali - I would recommend (not to say insist ) to disable CONFIG_ARM_ERRATA_430973 in rx51_defconfig until (and if) there is a need for it. Having this errata workaround enabled in KP brings only massive slowdown to the system, without any benefit, as there are no thumb-compiled binaries yet. And would you please make a new .debs with latest patches excluding those 6 from maacruz until I find which one brings the problems.
