Hello.

Recent change in suspend behaviour here I can 
attribute only to ACPICA MFC.

Previously resume left me with blank screen or non 
responsive one.

Now upon resume; from X11 or not, almost all is working, 
only thing that is stalled is pointer.

Also, I get CPU0 local APIC error 0x40 and upon restarting

calcru : runtime went backwards from (...)
for pid 1 (init)

Huge improvement from non-working suspend though.

best regards,
