Suspend does not work reliable for Palm pre

Description (last modified by morphis) (diff)

When trying to suspend the device (Palm Pre) with

echo mem > /sys/power/state

while the UI is running the command never finishes. Instead it hangs until it gets aborted manually with CTRL-C. Then the device goes into suspend. This is also the same behavious when the suspend is issued from fsousaged. Fsousaged hangs then when writing "mem" to /sys/power/state and is not responsible anymore.

Furthermore it's not possible to suspend the device when connected via ssh over usbnet. In webOS this is possible when using the novacom usb gadget driver.

When using directfb as display driver the suspend works without any problems. The problem seems to be somewhere the framebuffer handling of the Qt powervr and linuxfb gfxdrivers as both leads to the problem described in this defect.

There is now a workaround: We're using only the directfb backend for Qt4 until the bug is solved.
