Dear Josh, 

Thanks for your kindly reply, those error messages don't be occurred by specific SSD more likely random events. I got information form Intel VROC team agrees to support VMD hotplug in centOS 7.6 with kernel 5.02 in Purley Platform. The schedule is trending like Intel complete the validation and deliver the package by 11/20.

Therefore, we can close the event here, since it might be caused by OS kernel problem.
