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 2.6.21.1 on a Debian 4.0 ("Etch") system.
I thought that this might be related to ACPI. So I tried to boot with _only_
"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. So, can we please remove Dell Optiplex GX240 from the blacklist in
..../arch/i386/kernel/acpi/boot.c
? The attached patch does just that: It removes Dell Optiplex GX240 from the
ACPI blacklist.
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 to
work at full speed.
