This single test ran immediately after the boot and bug reproduced.

tst_taint.c:88: BROK: Kernel is already tainted: 512
https://lkft.validation.linaro.org/scheduler/job/293222#L1204

Test command for 10 iterations and it failed for all 10 iterations.
+ ./runltp -s cve-2017-17053 -I 10

NOTE:
We still see kernel warning while booting the x86_64 machine.
DEBUG_LOCKS_WARN_ON(sem->owner != ((struct task_struct *)(1UL << 0)))
