I just set up a fresh install of CentOS 7.2, and after doing
yum update, I can not boot into my machine. The kernel was updated, I can see both kernels in GRUB2, but I cannot boot into either of them, I cannot even boot into the rescue kernel. When I do the monitor goes black and does not come back, or stalls during boot and won't respond to any key presses. I think I forgot to do a
grub2-mkconfig -o /boot/grub2/grub.cfg possibly? Any advice?
Edit: single user works for original kernel. But if I try single user with new kernel the monitor goes black. I must have gotten a bad nouveau driver or something
