Okay, now that's just odd. You might try booting to the diagnostic partition and running the system through its paces there.

Tried acpi=ht again and it locks up before the kernel launches. Something here just doesn't smell right. Where exactly in the boot/install process does it die? Given that the IBM serveraid support isos boot linux, I'm a little shocked it's not working for you. HT should be disabled (in my opinion) as it's mostly useless. You might try resetting the bios settings to default, in case a tweak there has pushed something over. -- During times of universal deceit, telling the truth becomes a revolutionary act. George Orwell
