What version of the chipset do you have. The current ones can hang the PCI bus
during IDE transfers if you have IDE read/write prefetch enabled in the bios
setup.

It also has problems with the APIC implementation where an IRQ masked in
the APIC re-occurs which can hang the system. Worrying this one is marked
'nofix'. You might want to trying running "noapic"
