At first I just assumed that the kernel oops occured under all conditions, but on closer inspection I found that it only occurs when the modules are loaded before the modem is plugged in. So, to get things straight: 1) plug in modem 2) load modules 3) unload modules No kernel oops 1) load modules 2) plug in modem 3) unload modules kernel oops > > Here's an additional patch for 2.6.22, to be applied along with the > previous patch.
