Results from Linaro’s test farm. This regression is platform specific.
On arm64 dragonboard 410c-QC410E* the LT hugemmap05 and hackbench test cases started failing on this build and easy to reproduce. Where as on other arm64 platforms (juno-r2, nxp-ls2088) these test PASS.
These two test case scenario run on independent execution.
Steps to reproduce, cd /opt/ltp ./runltp -s hugemmap05
cd /opt/ltp/testcases/bin ./hackbench 50 process 1000 ./hackbench 20 thread 1000
Test output log:

Any chance you can run 'git bisect' to find the issue here?
