@leducp could you git bisect the bad commit id?

I'll do that when I'll manage to get a bit of time. In the mid time, I managed to workaround the problem by removing the "CONFIG_SCHED_HPWORK" option. I do not know what's the impact on the kernel but at least it let ostest finish properly without it :)
