I have a brand new Satellite L505D-S5983 which I'm trying to install

Hmm, that looks really unhappy..
If I boot with acpi=noirq these messages only continue for a few
seconds, although they cause a couple of initscripts to hang later on.
With ACPI fully enabled they keep appearing forever and the system
doesn't finish booting. With acpi=off they don't appear at all (but
the fan stays at low speed and the laptop gets quite hot if run for
more than a few minutes).
I've found only one other mention of this problem on the internet
(http://ubuntuforums.org/showthread.php?p=8358864#post8358864) from
someone with the same laptop as mine, but there was no working fix
posted to that thread beyond completely disabling ACPI. More research
told me that there used to be a way of fixing up the DSDT and having
it loaded from the initrd but the new policy is to just ask the
manufacturer to fix it and the kernel developers to work around it,
so... here it is. (Angry emails to Toshiba and Best Buy pending.)
Full dmesg output can be found at http://slexy.org/view/s25zU08AKJ
(By the way, what's the correct way to include dmesg output in a lkml
message if you don't know for sure which parts are relevant? Dumping
all 50k or so of it into the email seems like the wrong thing to
do...)
I think it's better if you file a bug report against ACPI at bugzilla.kernel.org.
Can you extract and post the DSDT in either raw or decompiled form, as
described here:
