  Boot will proceed through unlocking disk encryption. When graphical user 
interface starts, screen will go black and start spewing `unable to enumerate 
USB device on port` messages

  Test case B) In docking station, close lid and resume:
  =
  (Boot sequence done with laptop lid open)
  If laptop lid is closed before resuming from suspend, screen will soon go 
black and start spewing `unable to enumerate USB device on port` messages

  Test case C) Suspend without docking station (this one works):

2019-04-10 Thread Kai-Heng Feng
Possible to update the BIOS to its latest version (A25)?

Changelog for A18 says:
- Improved USB access stability.

So it may help.

2019-04-03 Thread Eero Aaltonen
Not new. It's been haunting me since I upgraded from 14.04 to 16.04. I
finally managed to make some sense of it and reproducible tests. Noticed
first at #1663555, but was unable to narrow it down.
