The tools impalements the mei state machine in the user space so it will conflict with the driver, you can try to unbind the driver if you need such functionality, Second the protocol is evolving and we are update the driver but I cannot update it in a tool I don't know about. I suggest you rewrite the tool using the driver interface. This is not connected in any way to underlying FW OS, this is about API. Thanks Tomas

intelmetool is for ME( desktop/laptop/etc) and we barely use it on SPS. We tested it on a pre-broadwell machine and it works fine. Could it be an issue related to the specific ME OS, e.g: the different impls of handling stuff from mei_me between MINIX-based and ThreadX?

First time I see it. My guess is this tool is for SPS and it will conflict with the mei driver on clients platform (mobile, desktop, workstations) It messes up the drive state machine, hence the error I've removed recently the BUG()
from the drivers so I guess on 4.20 it won't crash, but still this cannot work.
