--- Comment #13 from Todd Brandt (todd.e.brandt@...el.com) ---
Here's a method to easily reproduce this issue. The fstrim timer usually trips
at Midnight Monday mornings on ubuntu, so when testing happens during this time
we get this issue. Here's a way to trigger fstrim any time you want over
suspend/resume:

--------------
#!/bin/sh

/sbin/fstrim --listed-in /etc/fstab:/proc/self/mountinfo --verbose
--quiet-unsupported &
sudo sleepgraph -m mem -rtcwake 5
--------------
