[...] Das Aufschneiden selbst, für das eine Nagelschere nicht ausreicht, vielmehr schweres Gerät erforderlich ist, erweist sich dementsprechend als Akt höheren Berserkertums und erinnert an das Zersägen gefrorener Rinderhälften mit der Flex oder den Abriss einer Scheune mit der Nagelschere Kettensäge, so sperrig und spelzig stellt sich die Verpackung dabei an[...]
Again I got a little hardware problem :) This time it's the new shiny firewire harddisk i bought recently to do backups. If you connect your external firewire harddisk and get something like the following in your linux kernel message log then my patch could be something for you.

The problem with my disk (it's a Western Digital MyBook Studio Edition disk) is the spinup time. The disk needs some time to recover from suspend mode and the disk controller seems to block communication while this happens. The simple idea to get this sorted out is to increase the timeout the driver waits for the drive to answer. I increased the timeout from 2000ms to 5000ms and just get one error message at the beginning, but it works good after that first timeout.

The message that the driver cannot log into fw1.1 seems logical, since I've only one device connected but the disk has 2 ports to allow extending the bus with other devices
