--- Comment #3 from Jonas Jelten <jj at stusta.net> ---
Veeery interesting: I forgot I changed something else except those 4
parameters: intel_iommu=on, it was off before (because of playing with xen).
Now, with the iommu on again, it does not crash even after I enable my beloved
4 parameters again (yea i know, rc6 and the modeset is default now :)
To confirm, I just double-tested it with mmu=off again and keeping the 4
params, and yes it hung very quickly when watching youtube.
=> IOMMU on == good!
