dmesg on Toshiba NB555D
Hi, I had the same issue on my macbook, I came accross this link: http://wiki.alpinelinux.org/wiki/Error_message_on_boot:_Address_space_collision:_host_bridge_window_conflicts_with_Adaptor_ROM Essentialy the fix is to append pci=nocrs to your kernel boot paramaters. It worked for me. Using "pci=nocrs" is only a workaround and shouldn't be considered a fix. The host bridge window conflict error message should not cause a functional problem and can be ignored. I plan to reduce to a KERN_INFO message. I don't see the "ACPI: resource piix4_smbus [io 0x0b00-0x0b07] conflicts with ACPI region SMBI [io 0xb00-0xb0f]" message in the attached dmesg. It's not related to the host bridge window message. *** This bug has been marked as a duplicate of bug 729652 *** |
