Hrmmm...are there any known problems with the 2114x driver? I do see the following periodically: de0: abnormal interrupt: transmit underflow (raising TX threshold to 96|256) de0: abnormal interrupt: transmit underflow (raising TX threshold to 8|512) On: de0: rev 0x22 int a irq 9 on pci0.10.0 de0: 21140A [10-100Mb/s] pass 2.2 de0: address 00:60:67:30:75:ef In 100Mb/s mode... > I kinda doubt this > really has anything to do with CAM.
