Sadly, this seems to be a known error - open bug reports exist, but
as of the time of writing (May 23rd 2010) they haven't even been
allocated for investigation yet.
It appears to be most common on
ION-based graphics chipsets, such as the Acer Aspire Revo.

The
good news is that it seems to affect nothing beyond an irritating delay
on boot.
There was some thought that in earlier releases (<
10.04) you could defeat this through using lax ACPI settings, but that
seems to have no effect here.
