[ 1.130608] [drm:i915_gem_init_stolen [i915]] *ERROR* conflict detected with stolen region: [0xce000000 - 0xd0000000]
This afternoon while taking my dog for our usual afternoon walk - a good time for thinking - it came to me that I might be better off to remove the Intel driver. That way it would not matter if the Intel graphics were enabled, disabled, active, inactive or radioactive. In further support of this idea...
I purchase an identical machine to this a few weeks ago. I included an Nvidia Quadro K420 in the original configuration. I had it almost ready to replace my old CentOS 6 machine when I came across a BIOS corruption. Long story short after 4 hours working with Tech Support they had managed to brick the machine. Sent it back and order the one I currently have.
On this second machine I decided to try the Intel build in graphics to see if they would meet my needs. I installed CentOS 7.3. The Intel graphics did not suffice so I added the K620 card.
CentOS was installed onto the FIRST machine with the Nvidia card installed. Perhaps the install saw that and did not bother with the Intel graphics. That machine did not exhibit the error I am seeing on the second machine. The question is... How do I remove the Intel driver?
Here are the results of my investigation so far.
