Debian :: Squeeze Kernel Upgrade Broke Suspend To Ram

Yesterday, I ran a security update that upgraded my Squeeze kernel from 2.6.32-48squeeze8 to 2.6.32-48squeeze9.

Ever since then, my suspend to ram (STR) function is broken.

The machine will suspend normally, but will not resume. When I try to awaken the machine, I can hear the fan in the tower start up (the subject machine is a desktop computer, please see below for specifics), but the machine seems to be otherwise dead (e.g. the monitor stays blank, pressing the "caps lock" key on my keyboard does not activate said keyboard's "caps lock" led, Ctrl-Alt-F[x] has no effect, etc). My only recourse at that point is a hardware reset (ouch!).

I tried running Code: Select allpm-suspend from a terminal, with no joy. Same result running Code: Select allecho -n "mem" > /sys/power/state from a terminal.

I checked the /var/log/pm-suspend.log file and noticed that each Code: Select all...performing suspend line used to (before said kernel upgrade) be directly followed by a Code: Select all...Awake. line, but, now, all said Code: Select all...performing suspend lines are followed by an Code: Select allInitial commandline parameters... line.

Before this, STR has worked well ever since I first loaded Squeeze on this machine back in 2012.
