Title:
Dell Latitude E7240: Random hang on suspend
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
Ubuntu Trusty / 3.13.0-30-generic #55-Ubuntu
When suspending a Dell Latitude E7240 by closing the lid, most of the
time it will suspend fine. Sometimes it doesn't. When it doesn't, the
screen will remain on and will display the lock screen, but mouse
keyboard clock etc are completely frozen. Attaching a crash log from a
representative example.
This occurs somewhere between one suspend in every ten to one suspend in
every two. Occurs on both battery and AC power.
