Public bug reported:
I'm running Hardy Herron 32-bit Ubuntu, dual-booting on a Sony Vaio
VGN-C25 with Vista. None of the problems are present in Vista.
Neither the LiveCD or Hardy partition boots without manually adding 'acpi=off'
or 'acpi=ht'.
Adding 'pci=nopci' does not allow the laptop to boot. I have no /proc/acpi
directory.
When running Ubuntu, playing any audio repeats the first half-second
continuously until logout. This also applies to the logon 'drums' at the
gdm.
All battery applets give zero battery power remaining, though the
battery works. I have no power management access.
Laptop does not wake up from hibernation.
Power button does not work. 'Shut down' from within Gnome or gdm does
not power off laptop.
Wireless (not notification light though), bluetooth and Graphics card
all work fine.
