As far as I can tell from your corresponding skiboot patches, this is still the case after they are applied. Do we need a fallback to EEH_RESET_HOT in this case? Otherwise there will be no reset performed at all. Likewise, if the FUNDAMENTAL reset fails for any reason, should we fall back to a HOT reset? Regards, Daniel
