I believe the problematic kernels do actually boot. It just takes 12 to
13 minutes. dmesg shows several 120 second timeouts. Here is an
excerpt that shows the final timeout and then (presumably) the error
that is related to the hang.

If the battery is removed from the laptop, then it will boot and reboot
normally in a few seconds.
Another observation is that after the slow boot, the line "ACPI: Battery

My mention of the change to battery.c was actually between ubuntu
kernels 3.2.0-29 and 3.2.0.30 (ref browsing kernel.ubuntu.com/git) .
I'm not qualified on determining if it is related to problem -- it is
just as likely coincidence as far as I know but I did want to correct
the misleading version n
This looks similar to Bug #1093217. If the problem kernel will boot
with the laptop battery removed it could be the same.

I built a stock linux kernel from the latest at kernel.org (3.9.0-rc1)
and it has the same slow boot problem. One time I booted in recovery
mode and it was actually quick. I will report if this is consistent or
just a fluke after more trials. But in normal mode it is slow, about 20
minutes, and
Here is a possible workaround.
After reading up some on ACPI, I decided it was that the system got
stuck in the BIOSs’ ACPI code. This is what the error message showed
and I also came to the (possibly wrong) conclusion that this error was
there all along and other kernel changes actually fixed so
This DSDT fix also works in the recent kernel.org kernel (3.9.0-rc1).
With the fix that kernel boots fast and the battery is recognized. (Not
only did it boot slow without the fix, the battery was not detected).

The downside to setting legacy is that Windows cannot be loaded from the
grub menu. The upside is that the little nuvo button next to the main
power button on the Z580 makes it easy to get into the bios without
having to hit DEL or F2 or something before a timeout. So to switch

Yes I did, but I wanted the grub menu to still have the option to boot
without using the patched DSDT.
I put the patched DSDT in /boot/mydsdt.aml and changed

10_linux may be a little different in 12.10. I also have to watch o
Thats good and really the way you have it is all you need. I think you
might need to re-edit grub.cfg whenever the kernel or grub tools get
updated but that is not a big deal.

Matthew, here are some ideas.
First, remove the battery so you can reboot over and over without long
waits. If it does not boot faster now maybe it is a different problem.
Now the next thing is to prove the grub acpi command is working.
Restart and catch bootup at the grub menu. Then enter th

The AD57 is the hex length of the DSDT, or 44375 decimal . 44375 is
size of original DSDT. In the modified one it should be AD5B (44379
decimal). See what the size of /boot/DSDT.aml is. If it is 44375
