![]() The Panasonic AG-DV2500 tape deck contains an invalid entry in its configuration ROM root directory: A leaf pointer with the undefined key ID 0 and an offset that points way out of the standard config ROM area. This caused firewire-core to dismiss the device with the generic log message "giving up on config rom for node id...", after which it was of course impossible to access the tape deck with dvgrab or any other program. https://bugzilla.redhat.com/show_bug.cgi?id=449252#c29 The fix is to simply ignore this invalid ROM entry and proceed to read the valid rest of the ROM. There is a catch though: When the kernel later iterates over the ROM, it would be nasty having to check again for such too large ROM offsets. Therefore we manipulate the defective or unsupported ROM entry to become a harmless immediate entry that won't have any side effects later (an entry with the value 0x00000000).
