For what it's worth, we run into these FTDI panics with Monome devices all the time. I've called FTDI personally to discuss this with them (iirc it was about a year ago, and I'd been sending them panic reports for a solid 8 months before that) and they just don't seem to care.

No problems on Windows, and yes, the ftdi_sio module has been a part of the Linux source tree for quite some time (even OpenBSD has an FTDI driver).
