[Bug 989547] Re: Panda: suspend resume fails

 

The situation appears to be somewhat improved with the 12.06 final release candidate:
http://snapshots.linaro.org/precise/hwpacks/lt-panda-x11-base/139/hwpack_linaro-lt-panda-x11-base_20120626-139_armhf_supported.tar.gz
http://snapshots.linaro.org/precise/images/ubuntu-desktop/247/linaro-precise-ubuntu-desktop-20120626-247.tar.gz
I can now suspend the system to a state where most LEDs are off, only the ethernet LEDs remain active.  I pressed enter on the serial console and it started to come back up and was usable, however, after booting I had a constant stream of errors on the console:
[  615.714721] hub 2-0:1.0: unable to enumerate USB device on port 1

I'm not completely sure which USB it's describing, the only thing I have
plugged in currently is a usb mouse/keyboard which is working fine.
