Re: *ERROR* PCH transcoder A FIFO underrun

     Hello,

  You mean once I update to yet another kernel, things should be working again? Would you mind explaining the reason for this hope?

  Not sure about the quoted diff - I don't see how my problem is related to backlights?

  Thanks!

     Best,
     Oliver

     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,
