Resolved. Thanks for the suggestion. When I included the line clocksource=tcs, the problem went away. Also, when the machine booted up, I ran yum update and rebooted (without catching the grub menu) and the TSC error, again, went away, so maybe it is a problem with just that kernel ( Scientific Linux (3.10.0-229.20.1.el7.x86_64) 7.1 Nitrogen )?
