This issue is fixed by patch scsi: "core: configure runtime pm before calling
device_add in scsi_add_host_with_dma" I sent on Aug 3rd.

Severely lacking in the reviews department, though :(

Error message present in 4.8.0-rc3
Error message disappears after applying fix
https://patchwork.kernel.org/patch/9262149/ 
Would be good to merge the fix before 4.9.0 is released

Martin, the reporter considers this a regression, but according to
https://patchwork.kernel.org/patch/9262149/ you applied the fix to
4.9/scsi-queue – and it's not in mainline yet afaics. Was that an accident or
do you think this is not serious enough and thus better dealt with in 4.9?

I would like the change to get a bit of soak time before we backport it.

I'm seeing the same dmesg output too, on 2 machines with 4.8.0 rc7 / rc8
kernels.

It seems like this bug is preventing me on these machines to use any USB thumb
drives at all. In case anyone can confirm this I think it should go into 4.8.0
before release immediately.

Ok, I am not sure about this, there is a SELinux/Gnome issue involved and
probably other stuff too. Manually mounting the device works fine. So no, this
kernel issue is not preventing me from mounting the USB devices.

Can somebody confirm or deny that this is preventing you from mounting any USB
thumb drives?

This is preventing me from booting Ubuntu 16.10:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1631058?comments=all 

But I am not using a low-latency kernel.
