Bug Description
When booting (after kernel selection in grub2) the system is freezed. The screen became black and system seems freezed, but keyboard responds. Pressing Ctrl+Alt+F1 followed by Ctrl+Alt+F7 a stack dump will be showed. Please refer to the dmesg_from_
The PC is an Acer TimeLineX 4820TG
Ubuntu version is Natty Beta2 64 bits
Problem is reproducible :
1/ WithOUT power supply cable plugged, power on the Acer TimeLineX 4820TG under Ubuntu Natty Beta2 64 bits
2/ Under the grub kernel selection, choose 2.6.38-8
3/ Login and choose shutdown
4/ After PLUG the power supply cable and switch on the laptop
5/ Under the grub kernel selection, choose 2.6.38-8
6/ The system will freeze some seconds later

8/ Unplug the power cable, press Alt+Syst+B to reboot. Problem will not happen
Please note that at point 1/ if you switch on the machine with the power supply cable plugged, and at point 4/ unplug it, the problem will also happen!
Feel free to contact me in order to make further test. It's a regression, the problem doesn't happen under the 2.6.38-7 kernel.
