Bug Description

The entry "ACPI workarounds" that looks like:

    ${WriteMenuLst} "title ACPI workarounds" "title $(BootMenuACPI)"
    strcpy $kernel_line "$bootkernel $custominstallation $iso_scan_filename $automatic noprompt debug debug-ubiquity $commonoptions acpi=off noapic

should contain also the parameters ide=nodma all_generic_ide pci=nommconf to prevent SQUASHFS errors ( https://bugs.launchpad.net/ubuntu/+bug/172937 ). I think the parameter may be included in the "Normal mode" anyway because a lot of people is having problems, and the speed is unnoticeable

So it may look like:

    ${WriteMenuLst} "title ACPI workarounds" "title $(BootMenuACPI)"
    strcpy $kernel_line "$bootkernel $custominstallation all_generic_ide pci=nommconf $iso_scan_filename $automatic noprompt debug debug-ubiquity $commonoptions acpi=off noapic ide=nodma

Over the grub entry, I enter 'e' to edit the command and then launch it.

Changed in ubuntu:
status: New → Invalid

I got it to work by adding the following parameters to the kernel.

ide-core.nodma=0.1 ide-core.nobprobe=0.0 ide-core.nobprobe=0.1 pci=nommconf pci=noacpi

This is on a Toshiba satellite NB-10t. For Ubuntu 14.04.
