I was referring to Friedemann Baitinger's kernel messages showing the

I had said that messages coming down from an application cause this to
occur if the dev->tbusy flag is set. Then I was myself confused why the
messages were being passed to TR's dev->hard_start_xmit() function.
Generally the messages are not sent down from Linux networking software
when tbusy is set. However, there is a watchdog timer function that behaves
in exactly the opposite fashion: if the device is tbusy, the watchdog timer
initiates a call to dev->hard_start_xmit(), indirectly through a
"qdisc_restart" function. So you expect to see the messages once every five
seconds, the watchdog interval.
If possible I hope to someday fix the Adapter check situation to allow the
adapter to reopen; so it will be even less likely for any of us to get
stuck in an endless Arrg loop during startup.
