E1000_ERR "No usable DMA configuration, aborting\n";
File: e1000_main.c

Probable Causes:

Actions:

• "Verify driver software level"
• "Execute diagnostics"
  
• "Replace the adapter."

---

DPRINTK "The EEPROM Checksum Is Not Valid\n";
File: e1000_main.c

Probable Causes:

• "Unable to access pci data area for checksum value; however, the device id is valid."
  

Actions:

• "Verify Driver Software Level"
• "Execute diagnostics"
• "Replace board"
  

---

DPRINTK "Unknown MAC Type\n";
File: e1000_main.c

Probable Causes:

• "The MAC type is not ethernet as expected."
  

Actions:   

• "Verify the driver software level."
• "Execute diagnostics"
  
• "Replace the adapter."
  

---

DPRINTK "Invalid MTU setting\n";
File: e1000_main.c

Probable Causes:

• "Maximum transmission unit (packet size) is incorrectly set. This value must be between 64 and 16128."
  

Actions:   

• "Use ifconfig (or another network configuration tool) to set the MTU value within range."
  

---

DPRINTK "Jumbo Frames not supported on 82542\n";
File: e1000_main.c

Probable Causes:

• "You have configured the MTU size for a value appropriate for Jumbo Frames; however, the adapter does not support Jumbo Frames."
  

Actions:   

• "Use ifconfig (or another network configuration tool) to set the MTU value less than or equal to 1518."
  

---

DPRINTK "EEPROM Read Error\n";
File: e1000_main.c

Probable Causes:

• "Adapter h/w failure."
  

Actions:   

• "Verify Driver Software Level"
  
• "Execute diagnostics."
• "Replace the adapter."
  

---

DPRINTK "Warning: no configuration for board #%i\n";
File: e1000_param.c

Probable Causes:

• "The number of network adapters in the system that are associated with the e1000 driver exceeds E1000_MAX_NIC.  E1000_MAX_NIC is set in e1000_param.c, but can be overridden by the e1000_param.c module parameter."
  

Actions:   

• "Change E1000_MAX_NIC in e1000_param.c and rebuild the driver, or change the startup module parameter."
  

---

DPRINTK "Speed not valid for fiber adapters, parameter ignored\n";
File: e1000_param.c

Probable Causes:

• "Fiber adapters support 1000 Mbps only."
  

Actions:   

• "Use the default values with fiber adapters.  There is no need to set the Speed parameter."
  

---

DPRINTK "Duplex not valid for fiber adapters, parameter ignored\n";
File: e1000_param.c

Probable Causes:

• "Fiber adapters support Full duplex only."
  

Actions:   

• "Use the default values with fiber adapters.  There is no need to set the Duplex parameter."
  

---

DPRINTK "AutoNeg other than Full/1000 is not valid for fiber adapters, parameter ignored\n";
File: e1000_param.c

Probable Causes:

• "Fiber adapters support 1000 Mbps full-duplex only."
  

Actions:   

• "Use the default values with fiber adapters.  There is no need to specify AutoNeg."
  

---

DPRINTK "AutoNeg specified along with Speed or Duplex, parameter ignored\n" ;
File: e1000_param.c

Probable Causes:

• "AutoNeg and Speed/Duplex are mutually exclusive parameters."
  

Actions:   

• "Set either AutoNeg (Duplex=0) only, or set both Speed and Duplex parameter values, or set none of them."
  

---

DPRINTK "Half Duplex specified without Speed\n";
File: e1000_param.c

Probable Causes:

• "A Duplex parameter of 1 (Half Duplex) was specified, but no Speed parameter was specified."
  

Actions:   

• "Set the Speed along with the Duplex, or accept the defaults (1000/Full-Duplex for fiber, AutoNeg for Copper)."
  

---

DPRINTK "Full Duplex specified without Speed\n";
File: e1000_param.c

Probable Causes:

• "A Duplex parameter of 2 (Full Duplex) was specified, but no Speed parameter was specified."
  

Actions:   

• "Set the Speed along with the Duplex, or accept the defaults (1000/Full-Duplex for fiber, AutoNeg for Copper)."
  

---

DPRINTK "10 Mbps Speed specified without Duplex\n"';
File: e1000_param.c

Probable Causes:

• "The Speed parameter was set, but the Duplex parameter was not."
  

Actions:   

• "Set the Duplex along with the Speed, or accept the defaults (1000/Full-Duplex for fiber, AutoNeg for Copper)."
  

---

DPRINTK "100 Mbps Speed specified without Duplex\n" ;
File: e1000_param.c

Probable Causes:

• "The Speed parameter was set, but the Duplex parameter was not."
  

Actions:   

• "Set the Duplex along with the Speed, or accept the defaults (1000/Full-Duplex for fiber, AutoNeg for Copper)."
  

---

DPRINTK "1000 Mbps Speed specified without Duplex\n" ;
File: e1000_param.c

Probable Causes:

• "The Speed parameter was set, but the Duplex parameter was not."
  

Actions:   

• "Set the Duplex along with the Speed, or accept the defaults (1000/Full-Duplex for fiber, AutoNeg for Copper)."

---

DPRINTK "Half Duplex is not supported at 1000 Mbps\n";
File: e1000_param.c

Probable Causes:

• "The Duplex parameter was set to 1 (Half Duplex), but the Speed parameter was set to 1000 Mbps."
  

Actions:   

• "Set the Duplex value to 2 (Full Duplex), or accept the defaults (1000/Full-Duplex for fiber, AutoNeg for Copper)."
  

---

DPRINTK "Speed, AutoNeg and MDI-X specifications are incompatible. Setting MDI-X to a compatible value.\n";
File: e1000_param.c

Probable Causes:

• "The MDI value selected by the driver is incompatible with the settings of the Speed and AutoNeg parameters."
  

Actions:   

• "Look for a driver update.  The MDI value is defined by the e1000 driver.  Or accept the default values for Speed and AutoNeg.  The driver can autodetect Speed and Duplex."
