Comment 21 for bug 1594023

Ran into this problem on my Dell 7010 i5 desktop machine, after doing a fresh 16.10 install -- first time it's happened with any OS that I've run on it.

In my case, I'm getting DRDY ERRs on shutdown/restart. Hangs for several minutes with my SSD activity light lit up solid. Eventually the errors time out, and it shuts down, but it's a painfully long process.

I downgraded the kernel to 4.4.x for shiggles. The LTS enablement stack, graphic stack, and so forth were foobar, of course, but it otherwise booted and shutdown normally.

It smells like a kernel bug, to me, at this point. I'll investigate further and post back, if I can put a finger on it.
