[Bug 1384041] Re: [Dell Precision M3800] USB is dead after resume from sleep
I'd like to perform a bisect to figure out what commit caused this
regression. We need to identify the earliest kernel where the issue
started happening as well as the latest kernel that did not have this
issue.
Can you test the following kernels and post back? We are looking for the
first kernel version that exhibits this bug:
v3.13.11.6: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13.11.6-trusty/
v3.13.11.7: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13.11.7-trusty/
Thanks in advance!

Title:
[Dell Precision M3800] USB is dead after resume from sleep
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
After resuming from sleep (suspend to ram), all external usb ports are
dead.
The laptop's built in keyboard and synaptic touch pad (I think it is
vonnected via internal usb, but not 100% sure) still work.
Only a complete power down and reboot seem to bring back the devices.
The problem does not happen with the previous kernel 3.13.0-36.
