Created attachment 107344 [details] log of crash I have a device USB which implement with a microcontroller ARM a USB CDC-ACM. The implementation is not perfect, but with kernel 2.6 don't make me problem, with kernel 3.10 (I tried also 3.9 and 3.8 without success), I got a kernel panic, when the device is detached or I do a reset of the microcontroller. I attached the kernel panic in function handle_cmd_completion+0x502/0x95a module xhci_hcd. Thank you Giovanni
