But is the problem reproducible again if you re-upgrade?
The code that acpi-support runs on resume as a result of this update is:
# Get the power state into STATE
getState;
for dev in /dev/sd? /dev/hd? ; do
if [ -b $dev ] ; then
# Check for APM support; discard errors since not all drives
# support HDIO_GET_IDENTITY (-i).
if hdparm -i $dev 2> /dev/null | grep -q 'AdvancedPM=yes' ; then
if [ $STATE = "BATTERY" ] ; then
hdparm -B 128 $dev
else
hdparm -B 254 $dev
fi
fi
fi
done
it's not clear to me why any of this should trigger a hang on resume. Are
you knowledgeable with shell that you could try commenting out parts of this
code in /etc/acpi/resume.d/90-hdparm.sh, to find out which part is
responsible for the hang?
