It seems that the cooldown value is not in the 1-128 range... (the cooldown is used to regulate the rate at which paritymap updates get pushed onto the disk). I'm not sure why it is that high, or how it got that high :-( I'm also not sure if the kernel got that value from the paritymap on the disk or where... though I think if it read a '0' for the cooldown from the on-disk parity map that it would then use 'random garbage' from the newly initialized parity map if coming through rf_paritymap_attach() :( Fortunately, when the code detects these 'out of range' things, it grabs a set of correct values, and uses those going forward... Later... Greg Oster
