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...)

machines with "console=ttyS0,115200n8" fine here with no noticable
problems.

Again, any useful kernel messages?
