[Alistair Buxton <a.j.buxton@xxxxxxxxx>]

While messing around with this I noticed that the system does actually
unsuspend on recent kernels after exactly five minutes. After
unsuspending the system clock is five minutes slow, to the second. There
are no useful messages in dmesg, syslog or journalctl.

** Summary changed:

- close laptop lid = complete system freeze
+ system takes exactly five minutes to wake from suspend

** Description changed:

  To reproduce:
  
  1. Close laptop lid.
  2. Wait a couple of minutes.
  3. Open laptop lid.
  
  Result: the screen remains powered off and the system will not respond
  in any way. Pressing keys does nothing. Pressing the power button does
- nothing. There is no disk activity but the power light is lit. The only
- thing you can do is press the power button for four seconds or remove
- the battery.
+ nothing. There is no disk activity but the power light is lit. After
+ exactly five minutes (to the second) the system resumes.
