Problems on intel G33M motherboard

[lileding]

I got a new box with Core2 E6550
and the motherboard is a Foxtone G33M
However, the GENERIC cdrom of 6.2 Release can only start at ACPI disabled,
and USB keyboard sucks
and AT keyboard sometimes lead to crash during boot up
the worst is it cannot launch the other CPU core
with apic error

I also tried 7-PRERELEASE but still in vain

is there any patch ?
