Public bug reported:
Sony Vaio VPCEA3C5E
Normally suspending this laptop works fine, but if I have been using the
system a lot (lots of applications open, etc.) there is a high
likelihood that it will freeze when suspending.
The screen goes black and all disk activity stops but the machine is
still turned on and does not respond to any keypresses including trying
Ctrl-Alt-F1 or the power button etc.
The only way out is to turn off the power and boot again.
As this happens mainly when programs are open (it doesn't seem to matter
exactly what is open, just that the system isn't idle. Maybe when lots
of memory is used?) it basically only happens at the worst possible
times!
