I haveve recently updated my notebook from 6.1-RELEASE to
6-stable (RELENG_6).  Now when I power-down the notebook
("shutdown -p"), I get the following error message:

acpi: bad write to port 0x080 (32), val ...

It happens as the very last step after syncing the disks,
right before switching the box off.  i didn't get to read
the last part ("val ...") because the display switches off
after only fractions of a second.

Do I have to worry?  So far it doesn't seem to cause any

Best regards
