Ring any bells? I don't mind debugging the real issue, but good to know it's
not already solved. I didn't see anything on linux-usb archives, apart from
this:
https://lore.kernel.org/linux-usb/1566554761464.60146@xxxxxxxxxx/  which
doesn't look too familiar.

I couldn't recreate on v5.8, but this triggering this seems a bit fragile
even on linux-next.
Looks new.  Any chance you can run 'git bisect' to track this down?


Hi Greg,

I need to find a reliable reproducer. I could only reproduce when some other seemingly unrelated kernel config options were enabled. Let me see if I can reproduce based on Linus' kernel (it will be 5.9-rc now), and go from there.

Thanks,
John
