 On my Dell Precision M4600, the graphical boot seems to become stuck
in 1 out of 20 to 25 boots. Since there's nothing else to do, than to
force a power off, I have no further information about what fails or
become stuck.

the newest dracut should go into 'emergency' mode and then you can save the dmesg output onto an USB key.
Unfortunately I've done it before :D
