Hi,
I installed Centos 7 on my DELL E6420.
After the installation, I reboot my PC but at login the pc is freeze.
So I've to login in terminal mode (CTL-ALT-F2):
#dmesg|grep -i error
acpi PNP0A08:00: _OSC failed (AE_ERROR); disabling ASPM
I tried to install the kmod-nvidia, the NVIDA-official-dirver,etc....So I decided to install again the Centos 7 and reply to this post.
Thank you
