Hi,
With the ALPM patches I get: Unable to set link PM policy.
[until now I've tested only the combination of your, and Tejun's
port-stopping patch, as I already reported in a past thread]
It looks like my device doesn't support hipm, however it supports dipm.
If I make the change below, the ALPM patches work (i.e. no errors,
~0.5W and power savings).
Do you see any problems with enabling alpm on devices supporting dipm
but not hipm?
Thanks,
Edwin
