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. -- shpchp cannot reserve mmio region https://bugs.launchpad.net/bugs/577842 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
