Hello. I'm following up, but unfortunately cannot contribute back in a
meaningful way to this bug report, as I decided to go ahead with a clean
install.
Now, both pm-suspend and lid closing seem to work.
Note, however, that in order to get the wireless working reliable, I've
created the following script in /etc/pm/sleep.d/30_wifiup
#!/bin/bash
case "$1" in
suspend_hybrid|hibernate|suspend)
# executed on suspend
rfkill block bluetooth
;;
thaw|resume)
# executed on resume
# restart wireless, just in case
restart network-manager > /dev/null
#wake up the speakers
hda-verb /dev/snd/hwC1D0 0x1 set_gpio_mask 1
sleep 1
hda-verb /dev/snd/hwC1D0 0x1 set_gpio_direction 1
sleep 1
hda-verb /dev/snd/hwC1D0 0x1 set_gpio_data 1
#bluetooth
rfkill unblock bluetooth
;;
*)
;;
esac
I'm mostly adding this information just in case someone is searching as I did
for solutions!

Title:
After upgrade to 14.04, lid-closing suspend causes freeze
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
On a Macbookpro 11,1 running 14.04 lid-closure causes system freeze.
When I had 13.10 installed it worked without problem. I used do-
release-upgrade to upgrade to trusty and the problem started. I've now
tried installing trusty from scratch, but get the same behavior.
This does not happen when using pm-suspend to initiate suspend. I
consider this a security issue, as some users may be inclined to leave
their PC on rather than suspend and locking screen.
