Comment 4 for bug 577842

I have encountered the same error message and it prevents my computer from booting.
I have a Gateway DX4300-01H with an AMD Phenom IIX4 quad core processor. The
operating system is Ubuntu 10.04 with kernel 2.6.32-24. I have kernel versions going
back to 2.6.32-21 and the computer will not boot in either generic mode or recovery
mode with any of these versions. GRUB works fine and the computer starts to boot
but then freezes after the "Cannot reserve MMIO region" message. I tried booting with
all USB peripherals disconnected and that did not help. The problem seemed to start
with the upgrade to the 2.6.32-24 kernel but I have since been unable to boot with
the earlier kernels.

The computer is in a dual boot configuration with Windows Vista. It will boot with Vista
without error messages and all the internal and external hardware seems to work with
Vista.
