Bug Description
After creating a LiveUSB image and trying to boot it, unrecoverable squashfs errors are encountered because the usb stick disconnects. The laptop is a Dell Precision 5510 system (similar to the new Dell XPS 15).
I've not been able to get a full log in this situation, parameters like rootdelay= do not help although the boot process goes further.
The details below are after booting with toram which seems to side-step this problem. I haven't been able to get logs from the non-booting case yet because some key programs like mount do not get cached and therefore can't be found.
Steps to reproduce:
1. Create a 16.04 LiveUSB from daily image
2. Try and boot system from LiveUSB
3. Get lots of errors during boot because of the mass storage device disconnecting during boot
Expected behavior:
1. System boots into linux.

I haven't tried 14.04 which is what Dell ships these systems with. 15.10 has the same behavior though I did not collect any logs.
