So the patch does catch issues previously ignored.
I wonder what's the next move, maybe increase the ULP timeout again?
Kai-Heng, you can't simple increase ULP timeout. Why ME required more
time? We need to find ME expert and understand why FWSM (firmware
semaphore, bit 10 ULP_CFG_DN) indication take too much time. I wonder if
this indication work as properly. Please, try to understand. All
delay/timeout approach not acceptable.
Also, we communicated: : Intel vPro (vPro CPU + Corporate ME FW) system
(i.e. I219LM system) is NOT POR to support Linux
