Then we tried to reproduce this issue, finally reproduced it. [Fix] Intel debugged this issue as well, and they provided 4 kernel patches and a new firmware, we tested them, they really can fix the issue. And the patches were sent the SRU already, now it is time to update firmware. [Test Case] Install the system repeatedly and there is no hang issue anymore. [Regression Risk] Low, Intel told us there is no ABI change for the firmware, so it is safe to run this firmware both with the old driver (not applied those 4 patches) and the new driver (applied those 4 patches).
