    ACPI: Remove Dell Optiplex GX240 from the ACPI blacklist
    I have a Dell Optiplex GX240 and when I boot Linux, ACPI gets set up by only
    acpi=ht.  dmesg shows the following line:
       DELL GX240 detected: force use of acpi=ht
    Everything seemed to be fine.  However, I discovered that everything is not
    fine.  The USB controller works so slowly that copying a few (uncached) 1
    megabyte large photos from a USB-enabled digital camera takes many minutes
    instead of a couple of seconds.
    I am using Linux on a Debian 4.0 ("Etch") system.
    I thought that this might be related to ACPI.  So I tried to boot with 
    "acpi=force" appended to the kernel command line.  Voila, the USB controller
    started to work at full speed and copying photos from my digital camera took
    only seconds.
    I tested the system with "acpi=force" and could not find anything which did
    not work.
    I thought that this might be related to interrupts and APIC as well.  (Note
    that this is APIC, not ACPI.) I tried booting with _only_ "noapic" and
    "nolapic" appended to the command line.  Again, the USB controller started 
    work at full speed.
