Description Stefan Richter 2007-04-29 05:56:44 UTC

If two or more Linux PCs are connected to the same bus, ieee1394's nodemgr
repeatedly fails to detect that the present IRM is 1394a compliant and resets
the bus to become IRM itself.  This results in many resets and makes traffic on
the bus impossible before the bus settles down.

Workaround:  Load ieee1394 by "modprobe ieee1394 disable_irm=1" on N-1 of N nodes.

There are currently no resources to fix this in drivers/ieee1394/.
drivers/firewire/ is not known to feature this problem.

Comment 2 Stefan Richter 2009-01-14 09:11:49 UTC

Clarification:
Current drivers/firewire/ is known to work correctly in this regard.
