The message was added by me to track down possible cause of watchdog timeouts. The message means driver lost Tx completion interrupts but driver noticed that the queued frames were successfully transmitted such that it didn't reset the controller and showed the informational message. To further narrow down the issue, would you show me the following information? o full 'dmesg' output o 'pciconf -lcbv' output o 'devinfo -rv | grep phy' output
