This is a follow-up to my Ubuntu post from a few days ago. I've tried out the final version of 8.04 LTS on my Sony VAIO laptop, and found that it didn't boot. Instead, after the Loading Kernel process bar reaches 100%, the only thing that appears on screen is:
[ 42.947514] ACPI: EC: acpi_ec_wait timeout, status 0, expect_event = 1 [ 42.947575] ACPI: EC: read timeout, command = 128
And unfortunately that's where it ends. No CTRL+ALT+DEL, the only way to turn off the laptop is to hold down the power button for 5 seconds.
So apparently there's an issue with the ACPI, and indeed, it's something that's already being talked about.
I didn't actually install Ubuntu on the laptop, but I wanted to check it out from the live CD. My workaround is to hit F6 twice in the boot menu — once to get a command line interface to be able to add and modify the options, and the second time you get a popup. From there, conveniently select the first option, which is "acpi=off", by hitting Enter. Press ESC to close the popup, and hit Enter to boot. Of course ACPI will be disabled, but at least you'll be able to get into Ubuntu.

There seems to be a workaround that does not involve turning acpi off. Doing so messed up my audio card and my wired lan, which is why I don't like acpi=off.
Appearently, booting works when the external power cord is unplugged, a lot of peolple said, it worked for them.
Addiionally, removing the "quiet" option in the boot menue also solves the issue, and to my mind this is the best workaround thus far. Simply remove the "quiet" option in /boot/grub/menu.lst, that seemed to work for everybody.
