But after updating to CURRENT r317032 respectively r317559 suspend/resume does not work anymore. Putting it into suspend results only in a black screen, but no further action is possible (only pressing the powerbutton for some time to switch it off completely). The LEDs are not indicating any suspend mode. If i try to suspend it with X (intel-driver) stopped, the laptop does switch into suspend, but does not resume. It runs into some kind of resuming endless loop, where it tries to start the laptop again but at a certain point it restarts again. The screen stays dark all the time. I tried this with and without the following options but the same result. hw.acpi.reset_video=1 dev.acpi_ibm.0.handlerevents='0x04' Booting a Bootenvironment with an older CURRENT(r315141), all is working. Was there any change between these commits concerning suspend/resume? BR Manuel
