Thanks a lot for the quick fix! I ran my usual way to reproduce the
problem, and did not see it, so that's good! I do observe write speed
dips - eg we usually sustain 180 MB/s on this device, but now it
regularly dips down to 10 MB/s, then jumps back up again. That might
be unrelated to your patch though, I will run more tests over the
weekend and report back!

Best,
Martijn
