I have an XPS13 sitting that I don't use anymore. It's nvme as well, but
I don't think it's a Toshiba drive (nor is it 1TB). I will fire that up
with the new kernel as well and see if I catch anything. But it's most
puzzling if this is related to the drive, since I've run this on lots of
other nvme drives. I'm more inclined to think it's related to your dm
setup.

It's fine if you run the rest of the merge window like that, hopefully
I'll get something concrete out of some testing with dm.
