Bug 42906

During wakeup from suspend to ram, the kernel tries to load the firmware for my dvb usb adapter but fails. The adapter was plugged in at suspend and still is plugged during wakeup. I assume the root file system is not accessible again, so loading the firmware simply happens too early and needs to be deferred to a later point in time. No such problems exist when pluggin in the USB device at a later point in time.
