My problem is similar I have a USB KVM switch and if I switch beetween computers U got a Oops in evdev_disconnect (the first one is Kernel 2.6.23.12 and the second Kernel 2.6.24, both has this problem). My question is, can you tell me which two patches you have applied to solve the problem? I didn't found the right thing? Thank you very much for your help.
