No regressions on arm, x86_64, and i386. Regression on arm64 Juno-r2. Reported-by: Linux Kernel Functional Testing <lkft@xxxxxxxxxx> Following kernel panic noticed while running LTP controllers test cases on arm64 Juno device. Since this crash was noticed for the first time, I am re-running tests multiple times to check reproducibility.
