Summary

kernel: 4.4.110-rc1 git repo: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git git branch: linux-4.4.y git commit: 99abd6cdd65e984d89c8565508a7a96ea0fce179 git describe: v4.4.109-38-g99abd6cdd65e Test details: https://qa-reports.linaro.org/lkft/linux-stable-rc-4.4-oe/build/v4.4.109-38-...

Regressions (compared to build v4.4.109)

x15 - arm: ltp-syscalls-tests: * poll02 * runltp_syscalls

* test src: git://github.com/linux-test-project/ltp.git

The poll02 failure has been happening on 4.9/android/hikey since November 6th (4.9.60) and is under investigation in https://bugs.linaro.org/show_bug.cgi?id=3388.

It has never failed before on x15. I resubmitted the jobs to see if it is repeatable:

• https://lkft.validation.linaro.org/scheduler/job/89583
• https://lkft.validation.linaro.org/scheduler/job/89584

Both passed.

20 Iterations completed successfully on two devices. Which confirms this is an intermittent timing failure. https://lkft.validation.linaro.org/scheduler/job/89785#L3235 https://lkft.validation.linaro.org/scheduler/job/89786#L3245

Naresh/Milosz - I guess we should write a bug and see if it happens again?

Report bug with complete details. LKFT:stable-rc 4.4.110-rc1: x15: LTP poll02 FAIL: poll() slept for too long (intermittent) https://bugs.linaro.org/show_bug.cgi?id=3566
