I followed a suggestion in this bug report, appending the line GRUB_CMDLINE_LINUX_DEFAULT="initcall_blacklist=clocksource_done_booting" to /etc/default/grub , and running # grub2-mkconfig > /boot/grub2/grub.cfg Now I could re-boot into CentOS-7.2 with kernel 3.10.0-327.3.1.el7.x86_64 . -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin
