OK, so I definitely confirmed: if your patch does anything, it introduces a new deadlock possibility. Just trigger a Wifi timeout or reset from within remove(), and you'll see the work event get stuck in pci_reset_function(), while remove() gets stuck at cancel_work_sync(). I also confirmed that my patch resolves this problem. I'll send the revert + my patch now. Brian
