Haven't seen this one, no. I'm using a hardware console on the serial line most of the time (though I still haven't found the proper configuration and it's hardly usable for anything advanced making use of terminal features). > Haven't investigated it too much, but I've seen the odd case on Indy > and IP28 (which also uses the zilog driver) where shutting down my > serial client or sometimes rebooting the system running the client > oopses the driver.

It looks a bit like the serial driver crash on reboot which Martin Michlmayr fixed a couple of months back by backporting fixes from the sunzilog driver. But I think this one made its way into the kernel, so it must be something else.
