[Bug 581847] Re: system crash after changing power supply

[marco]

** Description changed:

  Hello,
  
  normally I use my ProBook 6545b without the battery, just with the AC/DC-adapter. But when I want to insert the battery and plug off the adapter (on changing the room) the mouse cursor will be like frozen before the screen turns black and the system will reboot.
  The issue only occurs when using the Ubuntu specific kernel of 2.6.32, which is used by Lucid.
  It didn't occur when using the mainline-kernel 2.6.32 or the previous version of Ubuntu.
  Please help me with finding the bug. If you have any code to test on my specific machine, let me know.
  Thank you.
  
  Marco
