Memory Access Collection: VTune 2020 sep driver generates messages about Linux Kernel

[Ketki_H_Intel]

I am running a workload on MySQL and collecting memory access data on Oracle Linux 7.7 my kernel version is 4.14.35.1902. I start the VTune 2020 collection by loading the sep driver and after 50 secs i.e at end of the run I am receiving these messages :

Message from syslogd.. 

kernel:Uhhuh. NMI received for unknown reason 20 on CPU 84. 

 Message from syslogd.. 

kernel:Do you have a strange power saving mode enabled? 

 Message from syslogd 

kernel:Dazed and confused, but trying to continue 

I also tried driverless collection ..it generates the .perf files it goes through fine without any messages. So I moved back to VTune 2019 and when I do the data collection with sep driver I do not see any messages generated by  kernel. 

Let me know if I am missing anything in my setup . I don't see these messages affecting my performance but not sure if this is expected !
