This should go to the linux-yocto list, since that's where<br>
people interested in the linux-yocto kernel variants will<br>
notice it.<br>
<br>
In this case, there was a bad merge. If you check the<br>
preempt-rt branches of 4.14 there's a fix queued, but I<br>
haven't sent SRCREV updates yet.<br>
