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. faugub_intel # iwork4intel

Hello,

Thank you for the information you shared.This is not a problem associated with hardware parts. The issue remains in the usage and allocation blocking tasks. This is something configurable in different ways and differs on the purpose of your system.I recommend to contact the Linux community for guidance on this topic. faugub_intel # iwork4intel
