In my case I also experience the problem after the machine has been asleep for some unknown length of time greater than a few minutes. But my FE acts as though it has dropped the UDP port connected to lircd on my BE, so it is unable to receive remote control keypresses. IIRC, things work perfectly from the keyboard.

Dan,
I think Your’s LIRC issue lays in LIRC HW reinit after S3 resume or… standby power on USB port during S3 sleep (if Your’s IR receiver is on USB port). 
What LIRC HW are You using?
