I am experiencing this issue every time I boot shortly after logging in
(~7 min). I'm on a physical intel machine, not a VM, running 14.04.2
LTS, kernel 3.13.0-53-generic
BUT I've also experienced this on:
3.13.0-54-generic
3.13.0-55-generic
The two previously referenced bugs are not found...
bug 1283129
bug 1283129
I've not been able to locate any log info on this issue. How can I
help. This is extremely annoying. My system is unusable in this state.
