I don't know if any of the ACPI error messages in your basic dmesg are 
relevant to this issue, or not.

It could be helpful to see the tail of dmesg, after booting with verbose 
logging, from before to after a suspend / resume cycle.  Among those 
messages will be RESET_KBD (and TEST_AUX_PORT and RESET_AUX, perhaps).  
These messages also appear after resume in /var/log/debug.log if verbose 
logging is enabled, and of course also in /var/log/messages.

A verbose dmesg would also show initial keyboard initialisation, perhaps 
a clue there?  Given you have two hdac devices, you'll almost certainly 
need to increase kern.msgbufsize from 64K to maybe twice that to get a 
full verbose dmesg, as kbd initialisation occurs very early.
