Running kernel 4.10.8-3.gea9dcd4 (from Opensuse's Kernel:Stable repo) on an Atom D525 box. I just noticed an OOPS on *shutdown*; Since it autoreboots, *boots* without problem, and I hadn't been paying attention until now, I can't say how long this has been occurring. On this box I follow the repo's current kernel-stable, and I'm fairly certain(ish) I didn't see the crash on restart in 4.10.7x series ... I only have access to two prior 4.10.8x kernels, and the issue exists for both. Chatting in ##kernel, suggested this is a new occurrence ... [ OK ] Reached target Shutdown.
