Title:
  New firewire stack unreliable with Texas Instruments TSB82AA2 IEEE-
  1394b

Status in linux package in Ubuntu:
  Incomplete
Status in linux source package in Maverick:
  Invalid

Bug description:
  Both controllers are tested okay working on an Ubuntu LiveCD
  environment (kernel 2.6.28-4-generic) and the old firewire stack.

  New firewire stack works reliably only for the Ricoh (internal)
  controller. The TI (PCI Express) adapter appears to work but then I
  see repeated messages filling up dmesg.

  I'm able to reproduce the issue exactly.

  1. Boot
  2. Connect storage device to internal (Ricoh) firewire
  3. verify that it is working by running command # dd if=/dev/zero bs=4k of=/dev/sdb count=16k
  NOTE there are no error messages yet
  4. Unplug storage device from internal (Ricoh) firewire, wait for it to settle
  5. Insert PCIE StarTech EC1394B2 (TI) controller, wait for it to settle
  6. Connect storage device to PCIE StarTech EC1394B2 (TI) firewire, wait for it to settle
  7. verify that it is working by running command # dd if=/dev/zero bs=4k of=/dev/sdb count=16k
  NOTE that there are repeated errors filling up dmesg

  This is the most often case. Infrequently, when I boot there is no
  problem using the TI firewire. After disconnecting and using the Ricoh
  and then back to the TI again, there are problems.
