I started with "acpi=off" and then tried many kernel parameters until I came up with the "intremap=off". It seemed that when apic took care of the interrupts the wifi would not work properly. Maybe, if "acpi=off" does the trick, you can also try "noapic" OR "acpi=noirq" OR "pci=noacpi", which also made wifi work in my case but with "collateral" damage (audio, bluetooth, brightness control not working).
