  [HP 4520S, 3.11 regression] Keyboard stops working after S3

Status in “linux” package in Ubuntu:

Bug description:
  After S3 on this laptop, the keyboard is completely non-responsive. (E
  g, Ctrl-Alt-F1 does not work) The trackpad is still working though.

  I believe this is a kernel problem because 
   1) It started happening recently, i e, it was not a problem when running with a 3.10 kernel.
   2) I can't find *any* keys working, not even magic keys (REISUB)
