[CentOS] Firefox and Thunderbird freeze/crash followed by "nfs4_reclaim_open_state: Lock reclaim failed!" syslog messages

I was afraid someone would say that :-).  I am currently at 
3.10.0-862.3.2 and downgrading to a 3.10.0-6xx kernel breaks some of the 
other packages.

Is the mentioned bug documented somewhere?

Cheers
frank
