I finally got a full dump on my own machine. It is a kernel BUG from
"scheduling while atomic". That makes me think that the bug is not in
rtl8187, but that unplugging the RTL8187 module triggers a bug in the
kernel.

I'm currently building the latest git pull of Linus's tree to see if
the problem is still there. If so, I will post on LKML and make a
kernel bugzilla entry.
