This patch breaks my box.. I'm not able to boot it anymore.
It seems with this patch I have /dev/sda[a-z] to /dev/sdz[a-z] ?!?
I'm not sure how to get an log since dracut times out and I'm dropped , after a
very long time
of probing 'ghost devices', in a emercency shell, journalctl doesn't work also..
After reverting this one I can boot normal.
Box is a FUJITSU PRIMERGY TX200 S5..
This is from an working kernel..
