System freezes before GUI login

Since few days I am experiencing a serious problem at boot time. The boot sequence interrupts right before launching the grapihic login interface, and the system freezes with the following three messages:

[ 0.061849] Ignoring BGRT: invalid status 0 (expected 1) [ 1.480861] nouveau E[ DRM] Pointer to TMDS table invalid [ 1.480863] nouveau E[ DRM] Pointer to flat panel table invalid

The system is a Lenovo Ideapad S510p, I have recently upgraded it to FC21 :

-> uname -a Linux ... 3.19.3-200.fc21.x86_64 #1 SMP Thu Mar 26 21:39:42 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

These are the graphich cards:

-> lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)

-> lspci | grep NVIDIA 04:00.0 3D controller: NVIDIA Corporation GF117M [GeForce 610M/710M/810M/820M / GT 620M/625M/630M/720M] (rev a1)

I only use KDE.

Note that I am using EFI, so I can have a dual boot (Windows 8 and Fedora). Everything worked for many months, despite some of the error messages above were still present. However, at some point the system refused to boot and froze. I then tried a "yum update", hoping that it was barely a problem of obsolete drivers, but it did not not help.

Where is the problem? How to fix it?

Many thanks in advance for any useful suggestion!

Hi, does the problem show ups right after the upgrade or were you able to use the systems after the upgrade? Have you tried booting with an older kernel? It looks like a video driver problem. Kind regards
