As i wrote i still use parameters. ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 For me i couldn't boot with anything other then pci=noacpi before, but now ivrs parameters work and i got a working touchpad. "Things seem to work" is because i have only used the laptop for a day and i haven't tested every single scenario, but as far as i can tell it works. I wasn't able to boot with ivrs parameter before and i had no use of the laptop that was only useful as an paperweight, it couldn't suspend or hibernate. Now i have a working laptop that i can finally use and no fans going berserk.
