| "dc%d: couldn’t map ports/memory" | A fatal initialization error has occurred. |
| "dc%d: couldn’t map interrupt" | A fatal initialization error has occurred. |
| "dc%d: watchdog timeout" | A packet was queued for transmission and a transmit command was issued, but the device failed to acknowledge the transmission before a timeout expired. This can happen if the device is unable to deliver interrupts for some reason, of if there is a problem with the network connection (cable or network equipment) that results in a loss of link. |
| "dc%d: no memory for rx list" | The driver failed to allocate an mbuf for the receiver ring. |
| "dc%d: TX underrun -- increasing TX threshold" | The device generated a transmit underrun error while attempting to DMA and transmit a packet. This happens if the host is not able to DMA the packet data into the NIC’s FIFO fast enough. The driver will dynamically increase the transmit start threshold so that more data must be DMAed into the FIFO before the NIC will start transmitting it onto the wire. |
| "dc%d: TX underrun -- using store and forward mode" | The device continued to generate transmit underruns even after all possible transmit start threshold settings had been tried, so the driver programmed the chip for store and forward mode. In this mode, the NIC will not begin transmission until the entire packet has been transfered into its FIFO memory. |
| "dc%d: chip is in D3 power state -- setting to D0" | This message applies only to adapters which support power management. Some operating systems place the controller in low power mode when shutting down, and some PCI BIOSes fail to bring the chip out of this state before configuring it. The controller loses all of its PCI configuration in the D3 state, so if the BIOS does not set it back to full power mode in time, it will not be able to configure it correctly. The driver tries to detect this condition and bring the adapter back to the D0 (full power) state, but this may not be enough to return the driver to a fully operational condition. If you see this message at boot time and the driver fails to attach the device as a network interface, you will have to perform a second warm boot to have the device properly configured. Note that this condition only occurs when warm booting from another operating system. If you power down your system prior to booting
.Fx , the card should be configured correctly. |
