I managed to boot linux without kernel panic with no acpi=off. I was wandering in the bios settings when i tumbled over "Interrupt 19 Capture" that was "disabled". Enabling it "resolved" the kernel panic. I would like to stress that the bug is still present whether it can be a bios or a kernel bug.
