Hello,
Thank you for contacting Intel Customer Support.
Based on this lines, I could say it is associated to the way drivers will allocate and manage memory. GFP_NOIO and GFP_KERNEL will change the blocking level and has many usages.
I would like to know what Intel product you have, your system configuration and any other detail you would like to add, so we can better assist you.
