Just in case of, the command line I'm using is

ro root=/dev/sdb2 rootfstype=btrfs rootflags=compress=zlib enforcing=0 
selinux=0 cgroup_disable=memory swapaccount=0 
earlycon=uart8250,io,0x3f8,115200n8 console=ttyS0,115200n8 console=tty0 
memtest=3 LANG=de_DE.UTF-8 video=DVI-D-1:1920x1080-32@60

And memtest never failed (I'm always using that). So it's unlikely it's 
a problem with the memory.

But usually I don't have enabled the serial, that means normally I'm 
booting with

root=/dev/sdb2 rootfstype=btrfs rootflags=compress=zlib enforcing=0 
selinux=0 cgroup_disable=memory swapaccount=0 console=tty0 memtest=3 
LANG=de_DE.UTF-8 video=DVI-D-1:1920x1080-32@60

so maybe enabling the serial does something bad. Also I've enabled it 
before and haven't seen something bad. And because I assume the IOMMU is 
the problem, I don't use any cards, just the HW on mb.

Alexander Holler
