Just had a problem with CentOS 6.5 x86_64 after the last kernel upgrade. It looks like the boot sector got hosed somehow and the system was unbootable. I was able to fix it with a boot to an install image USB and running grub-install. System is now bootable. However, I've lost the system console. No login prompt is provided at the console. The system boots and is remotely accessible. Services seem just fine. I don't see any error messages after booting, either dmesg or /var/log/messages. Can anyone tell me what packages provide console login so I can try a reinstall. Thanks.
