Turns out the problem was a line in rc.local where I was forcing the GPU
into low power mode:
echo low
/sys/class/drm/card1/device/power_dpm_force_performance_level
Took out the kernel parameters and ran in single user but didn't catch
that. Leaving radeon dpm on auto or setting it to high
The /var/log/dmesg.log.1 file doesn't seem to be updated in single user
mode, but it doesn't get any extra output from the suspend when it is.
Or are you looking for the output of dmesg at boot from each of the
various test runs I did? I gave it a quick go on 3.13.0-30-generic in
single user and
I'm still lacking the dmesg of when things go wrong, could you attach
that?
