thinkpad_acpi: WARNING: sysfs attribute hotkey_enable is deprecated and will be removed. Hotkey reporting is always enabled

After upgrading Ubuntu 10.10 to 11.04, after changing from Finnish locale to UK locale. Using International Dvorak. Run System Test and the crash occurred.

There does not seem to be Correct Keyboard -option for X60, Lenovo IBM. There is T60 and such, but no X* -series. It is likely that the problem is caused the keyboard setting.

Very strange crashes, about 4, have occurred today with the given X60. Not sure whether they are related to the graphic card, since I do not have a new X60 to test it.

Problem may also be caused by upgrading process from 10.10 to 11.04. I run at the very end of the process Software center and tried to install Compiz, while the upgrading was going. Some data corruption may have happened, since the process did not seem to go to the end.
