Hi Remi,
I've discussed this with mpi. We're unsure what's going on exactly.
Can you please really make sure you're not dropping into ddb (i.e.
don't detach the device while in X, but when on console)?
Can you please apply this diff and let us know if you see any STATUS=?
lines with it when the problem happens (again, console, not X)?
Thanks.
