Not sure if this was the last email on this.  If not ignore me. However I found a post for new operating systems that says to set the watchdog_thresh value instead of softlockup_thresh.  
http://askubuntu.com/questions/592412/why-is-there-no-proc-sys-kernel-softlockup-thresh
this is an Ubuntu post, but on my CentOS 7 system this parameter exists, and softlockup_thresh does not.  I have set it but I will need to see if I still get the CPU lock up messages on my VM.
I hope this helps.KM

Yes, I tried it, but does not exists:

vmguest # cat /proc/sys/kernel/softlockup_thresh
cat: /proc/sys/kernel/softlockup_thresh: No such file or directory
