Youkon controllers seems to have silicon bugs for hardwares with RAM buffer. msk(4) in HEAD has workaround code for the silicon bug. Would you try latest msk(4) from HEAD?(Just copy if_msk.c/if_mskreg.h from HEAD to your box and rebuild kernel.) Also show me verbosed boot message(msk(4) related one would be enough). -- Regards, Pyun YongHyeon
