This sounds very much as if you got your keyboard into scancode mode 1.
(Ordinarily a key-up event gets scancode of key-down but with high-order bit set. In scancode set 1, a key-up event get the scancode of key-down prefixed by 0xf0. Since the high-order bit is masked here, this 0xf0 would show up as 0x70. Moreover, the key-up for a sequence like e0 71 is e0 f0 71, again what you see here.)
How you got into scancode mode 1 I don't know (maybe by sending the command f0 01 to the keyboard). Do things improve if you rip this strange messy AUX_RECONNECT stuff out of drivers/char/pc_keyb.c?
