Description
WIth CP.3.0 master and 20180110 Bundle release I am running into a problem on my Metro M4 Express.
Every time I try to import adafruit_ssd1306 the system hangs then eventaully dismounts the FS and dmesg reports a read error. I have recreated and relaoded the FS several times and this is very repeatable. I am using the "py" version of the bundle, but I did verify that is also occurs with the .mpy version.
I am able open and read the lib/adafruit_ssd1306.py file.
I have run a few other program that import library modules with no problem.
After a reboot, the FS appears to actuall be OK. I can still open and read adafruit_ssd1306.py.
I just did a git pull of the master before testing this:
`Adafruit CircuitPython 3.0.0-alpha.1-53-gd201ac2-dirty on 2018-01-11; Metro M4 Express with samd51j19
import adafruit_ssd1306
system hangs until FS is dismounted
dmesg output:
694491.780411] FAT-fs (sdc1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.
