What else is plugged in? The top line of the log snippet you sent
shows an error from a USB video device... I wonder if the error
occurred in a different part of the stack, and it just finally
bombs-out in usb-storage....

I've had several lock-ups on recent 4.12.0+ kernels that I've built.
The machine has an Asus M3A78 Pro motherboard and 4-core AMD CPU.
The only usb-storage in use is an external Seagate HDD with one ntfs-3g
filesystem and another ext3 filesystem mounted.
A recent kernel log showed:

I haven't been using the DVB-USB stick, it's just been plugged in
whereas the usb-storage had its filesystems mounted.
I've since un-mounted the usb-storage filesystems and did:
modprobe -r uas
which also removed the usb-storage kernel module, to see if that
prevents further lock-ups.
