Bug Description
We expect this firmware update could be released with 19.10
[Impact]
We have a couple of Dell machines, after installing the system, it
will hang randomly, and this issue was reported by factory, they met
this issue a couple of times. 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).
