Well, in my case I have legacy free BIOS, so it is not in SMM mode, and USB controller seems to be connected to PCI IRQ line and generating interrupts. For UHCI though patch resets the controller, thus disabling interrupts, and fixing the problem. It might not work for OHCI in legacy free system, since there is no reset/interrupt disable for it in the patch. Let me know if I missed something... BTW, I talked to BIOS developers on this. They basically recommended 2 possible solutions: - try to not share UHCI irq line or - enable native support (or at list disable interrupts) early during boot.
