Hi Robert, Code from git master will not call pxa27x_keypad_config on resume if device can cause wakeup, so everything is OK (however it's another issue for pxa27x, because device is not resuming correctly) > And I suppose you can't "convince" your bootloader to behave correctly, can you ? It behaves correctly, it just can't handle last keypress (because it's booting Linux). Even if it would be possible to fix this issue in bootloader it's always nice to keep driver failure-proof, so it does not fail even if bootloader left something in non-consistent state.
