nodes crash using SEP collectors after Meltdown/Spectre patches

After patching our OS for Meltdown we're seeing nodes crash during amplxe-cl collection using the HW counters (any of the non-PIN collections)

PIN collections work ( simple hotspots )

Also, using the older 2017 Update 1 VTune and collectors there are no issues.

But 2018 Update 1 with event counters crashes the node almost immediately after start of collection on any application. 

SEP drivers were not rebuilt after the Meltdown kernel patches - perhaps that is a test to do?

Anyone else seen this behavior?  Nodes crash hard and have to be power cycled.
