Your Ubuntu kernel is clearing the host protected area (the BIOS has
marked the end part of the disk as 'reserved' - probably for an XP
restore partition), the base one for some reason is not.
Set the boot option "libata.ignore_hpa=1". That defaults to zero
(respecting the BIOS) so that users don't accidentally blow away BIOS
partitions and restore images, except apparently Ubuntu patch it the
other way by default.

Not so. All of my drives are larger than that, with a sata sdc of 400GB that
dmesg reports as:
[ 8.103237] ata4.00: ATA-7: Hitachi HDT725040VLA360, V5COA7EA, max UDMA/133

I've never seen this error here, and I've built everything recently but 24.7.
I only keep .25 and later stuff although there may be some leftovers in /boot
I haven't removed. My latest in the .24 series in .6, and it didn't do that.
Perhaps you don't have all the big file stuff enabled in your .config?
Running 2.6.26-rc1 ATM here.
