It's a huge diff, will not fit on this list I think :( Anyway, I just looked at it again. Marco, there are numerous bugs in that driver code. NEVER have an empty release function for a device, that is completly wrong, and is one reason why this is now failing. Your driver also has devices in the __initdata section, which is being thrown away by the kernel. That's probably the biggest problem and I'm amazed it even worked at all here. thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-hotplug" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
