I don't know what is wrong. I have the same problem since I updated from
Slink to Potato. Somehow the module sb tries to use IRQ7 even if I try
to set IRQ5. The same kernel (2.2.14) and the same configuration worked
well with Slink. Perhaps there's a bug in one of the packages (isapnp,
modutils ???).
