Hello,

  On trying to boot, Fedora crashes on my Lenovo Thinkpad T430 with this message:

Booting 'Fedora (3.15.4-200.fc20.x86_64) 20 (Heisenbug)'

[   2.718947] [drm:cpt:cpt_serr_int_handler] *ERROR* PCH transcoder A FIFO underrun

  Actually, all kernels after 3.13.10-200.fc20.x86_64 are crashing on boot on my laptop, but this is the first time I get an error message. Plus, I also have random crashes a few times per day.

  Any ideas? Thanks!

     Best,
     Oliver
