Outstanding .. I have now released a 4.9.23-26.el6 and .el7 to the
system as normal updates. It should be available later today.
<snip>
Current tested kernel was: 4.9.13-22.el7.x86_64 #1 SMP Sun Feb 26 22:15:59 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
I just attempted an update and the 4.9.23-26 is not yet up. Does this update address the Hyperthreading issue in any way?
Thanks
PJ
