How did this ever work?
Detaching the ll driver from the tty port in this manner is not ok;
as you already note, it blows up if consoles are still running.
No one unbinds serial drivers using serial_core, as all these drivers are
for fixed hardware?
Yep, never tested until now :)
Do you need this to work?
Hot-pluggable usb-serial doesn't use serial_core.
I guess none of the 8250 PCI adapters are hot-pluggable...
