I'm running the following hardware:
MSI 890FXA-GD70 motherboard With a AMI v1.7 BIOS AMD Phenom II X6 (1055T) 8 GB RAM (2 x 4 GB DIMM) nVidia Geforce 7300 (G72) video Card ViewSonic VA2431wvm monitor Plus
The OS is:
CentOS release 6.3 (Final) 2.6.32-279.5.2.el6.centos.plus.x86_64
Actually, on this machine I'm getting the following error during bootup:
[drm:drm_edid_block_valid} *ERROR* EDID checksum is invalid, remainder is (222; 122; 251; but mostly 128)
From time to time the video locks up and sometimes goes black. But the keyboard and mouse usage can be seen via lights blinking whei I enter something on the keyboard. And I can see what I entered when the display returns.
I know the monitor, keyboard, and mouse are not the problem because I have 3 machines on a KVM using the same monitor, keyboard, and mouse. Could this be my video card going bad? I read another posting where it was suggested to add 'Option "IgnoreEDID" "1"' into the xorg.conf, but this machine doesn't have a xorg.conf file.
Any information will be helpful.
