Bug Description
[Impact]
We have several crypto accelerators for Hisilicon 1620 but unfortunately one of them is not mature and causes stress-ng tests failure. Disabling hisi_sec2 makes kernel to run crypto functions without accelerator.
[Fix]
Disable CONFIG_
[Test]
$ sudo stress-ng --aggressive --verify --timeout 330 --metrics-brief --tz --times --af-alg 0
$ echo $?
[Regression Potential]
This driver is only loaded on Hisilicon Hi1620 machines. Low risk for other platform.
