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_CRYPTO_DEV_HISI_SEC2 temporarily until we have proper driver.
[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.
==================================
[Bug Description]
CPU stress test fails with focal kernel
[Steps to Reproduce]
1) sudo apt-add-repository -y ppa:firmware-testing-team/ppa-fwts-stable
2) sudo apt-add-repository -y ppa:hardware-certification/public
3) sudo apt install -y canonical-certification-server
4) Install focal kernel debs from https://launchpad.net/ubuntu/+source/linux
5) Run CPU stress test with `sudo certify-advanced`
[Actual Results]
Failed with
stress-ng: fail: [6118] stress-ng-af-alg: bind failed, errno=19 (No such
device)
[Expected Results]
Passed
[Reproducibility]
100%
[Additional information]
Same test with bionic-update kernel passed
