Wonderful, thanks for letting us know. It's been in linux-next since
Tuesday of this week. Perhaps your testing could see if patches
further along in the specific branch you hit solve the problem you are
having before you need to report the issue?

Yes, good idea! It could be made more smart like that.

Thanks,
