There are two sets of results:
1. After a reboot but before suspend/wakeup

/sys/bus/iio/devices/iio\:device3/in_accel_?_raw`; echo; sleep 1; done

-898143 278906 15722
-648143 683203 123144
2. After susepend/wakeup, output from cat seems to take a long while
(10+ sec for each cat call)
0 0 0
0 0 0 and so on...

1. Before suspend/wakeup: see attachment sensor-monitor_output1.txt
2. Post suspend/wakeup:
