Those kinda look like the driver is still trying to communicate with the device like it's still there. Are we sure the driver is getting the disconnect callback? The fact the two messages above repeat might be because of the slab cache for QHs and TDs. It might just be getting allocating the same memory over and over again. > > > Any ideas of how to fix this, or even what is causing this continuous > > > message (I can see it happening once, but not more than once.)

It doesn't look like that now that I look at it.

Neither have I. Can you possibly add some debugging to see if the disconnect callback is being made? I would expect this behaviour if the driver never gets told that the device was disconnected.
