Public bug reported:
This is a weird one, but...
I have a Lenovo T410s laptop, that I've run every release from 11.04 to
current 12.10 development code on. Suspend/resume has pretty much
always worked, except apparently with the latest Quantal kernel there is
a regression. The computer continues to suspend fine -- when I close
the lid, the "moon" / sleep LED blinks and then turns on as usual.
However, when I open the lid, which has always made the computer try to
wake up, it just stays asleep -- sleep LED solid on, power button LED
smoothly pulsing on and off. Even pushing the power button does not
wake the system -- the only thing that makes it respond is holding the
power button down long enough to force a hard power off, and then it
reboots normally (but of course it's a cold boot, not a resume of my
suspended state).
I really don't know much about how laptop suspend/resume works -- could
something have broken enabling wakeup sources? Does that make any
sense?
I'll try the upstream kernel package and report back too.
