    WARNING: at drivers/gpu/drm/drm_crtc_helper.c

    952774
      Hi.
      I am new to the administration Linux.
      Version OS - Oracle Linux 5.8
      Linux version 2.6.32-300.39.2.el5uek
      I installed the update two days ago.
      Today, after a reboot, I found the following messages.
      I do not understand the messages.
      Tell me what it could be and where you can read about it.
      Thanks in advance.

          Did you update the system or is this a new installation? Please keep in mind that Oracle Linux is for enterprise grade hardware and not designed for desktop or mobile computers. Isn't the Intel i915 built-in graphics controller typical for desktop grade hardware?

          To address your problem at hand: You can try to add "i915.modeset=0" to your kernel parameter line to disable DRM, which usually helps. You can add the parameter temporary at the Grub boot menu or editing /etc/grub.conf

          Btw, are you running Oracle linux 32-bit instead of x86_64? Why?

            Yes you are right, Linux 5.8 64bit installed in desktop.
            This is a test machine for learning Linux.
            In our company we have industrial circuit Hyperion consisting of four servers.
            Linux 5.8 64bit is deployed on three servers blade system.
            They work steadily and reliably.
            next week will be a stop circuit and work on its modernization.
            Also be held updatings Linux installation.
            So I decided to check out how it all goes, but you can see it's not the same thing.
            Thanks for your the answer.
            I will study on Linux

              I think your best option for learning any OS without jeopardizing the operation of your computer and daily work will be VirtualBox https://www.virtualbox.org. It provides an environment that will install Oracle Linux without any compatibility issues and allows you to easily restore from existing snapshot backups should you screw up your guest system.
