    Interesting. Not had a report of that thus far. Can you send me any
    kernel messages relating to serial devices please, and the bad address
    that caused the oops? (line 189 is obviously a lie...)

    Weird. Currently I've no idea what's causing this; I've been booting
    machines with "console=ttyS0,115200n8" fine here with no noticable
    problems.

    Again, any useful kernel messages?
