I have the same issue with a similar computer configuration and Gutsy
64-bit, but happens only when I have memory remapping enabled (needed
because of 4 GB of RAM) in the BIOS. With memory remapping disabled it
detects only 3.3 GB but everything is OK.
The newest 2.6.22.10 kernel doesn't fix this bug.
This bug should also be reproducable with: "dd if=/dev/zero of=test
count=5000 bs=1M" but I'm not certain. i will investigate further.
A more exact entry in syslog I get is:
