Hi everybody!
I've installed uphuck v 1.4r3 on an Acer Aspire 5622WLMi (Intel Core Duo T2300, Ati Mobility Radeon X1300, 1GB DDR2).
Installation process works fine but on first boot freezes on a screen with a grey background and the apple logo on center and Cpu seems to be not operative.
I tried to boot on -v mode and i realized that "freezing" happens when these lines are displayed:

IOAPIC: Version 0x20 Vectors 0:23
Started Cpu 01

So how can i solve this problem??
Thanks to everybody!
