Comment 12 for bug 1420290

The error occured twice in the last 24 hours:

$ cat /var/log/kern.log | grep -i flip

I checked if there is correlation with logging about "Lid":

$ dmesg -T | grep -i Lid
[di mrt 3 07:00:31 2015] Ignoring BGRT: invalid status 0 (expected 1)

[di mrt 3 07:45:32 2015] systemd-logind[1250]: Lid opened.

I see no correlation, but I do some strange things:
"Lid closed." and "Lid opened." in that order immediately after each other (within 0.1 second). That looks untrue as I don't do that.
I really opened the Lid this morning around 07:00, but it is not in dmesg. Weird.
