Description Stefan Richter 2008-06-05 15:55:21 UTC 
The PL-3507 FireWire-to-IDE bridge chip is known to sometimes become unresponsive despite our drivers sending a fetch agent reset.  To do:
  - find a way to inject such failures,
  - find a method which gets the PL-3507 unstuck again.
(Target reset via RESET_START register perhaps?)
Comment 1 Alan 2012-05-21 15:44:55 UTC 
Is this bug still relevant ? If so please update the kernel version to something meaningful
Comment 2 Stefan Richter 2012-05-21 16:51:54 UTC 
Still somewhat relevant.  I had two PL-3507 devices with different firmwares, one died a while ago, the remaining one has a comparably good firmware and may therefore not be a good test specimen for this.  Besides, there is so much else to do.  I am closing this bug but made a note at https://ieee1394.wiki.kernel.org/index.php/To_Do#firewire-sbp2 .
