I have a simple setup with an RP2040 feather controlling some neopixels and am trying to get it to reliably deep sleep when not in use. I have a vibration switch between GND and A2, and am sleeping until the vibration switch gets triggered using

pin_alarm = alarm.pin.PinAlarm(pin=board.A2, value=False, pull=True)
alarm.exit_and_deep_sleep_until_alarms(pin_alarm)

This works great and my current consumption goes from ~28mA to ~2mA once it gets to sleep. But if I happen to trigger the vibration switch while it's in the process of going to sleep it seems to go unresponsive. Current consumption still goes down to ~2 but it no longer wakes until I toggle reset. Ive confirmed that the pull-up resistor is getting configured correctly (I see 3.3v on pin A2).

This problem is extremely reproducible on this setup, if I give it an extra second after the current has dropped down it seems to wake every time, but if I spam the vibe switch while it's getting ready to sleep it pretty consistently gets locked up.

Everything works as expected when connected to serial and using simulated deep sleep.
