[Bug 642091] [NEW] Acer Aspire One 721 - no resume after suspend

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

Acer Aspire One 721
Ubuntu Maverick 10.10 beta, 32bit

When putting the laptop into standby, everything works - the screen and
-backlight are deactivated and the power led flashes slowly.

When trying to resume, the power light comes back to it's normal state,
but neither the harddrive LED nor the screen are reactivated. This
happens every time.

I ran the system through this test:
https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume

stage 1: 
The system does start going into standby (deactivating screen), but does not really go into standby (where the power LED would slowly blink). After the screen goes on again, I have the following problems:
- touchpad running wild (touching it opens multiple new windows, etc)
- wireless is deactivated in nm-applet

Stage 2 test:
- no resume possible (any button presses have no effect), the system stays in standby (no return of the power LED from slowly flashing to "on" state)

Stage 3 test - same effects as the normal standby:
no resume possible (the power LED comes back from slowly blinking to "on" state, but screen stays blank)

Any hints?
