Errata—Intel
®
82599 10 GbE Controller
Workaround:
None.
Status: B0=Yes; NoFix
26 82599 Might not Be Recognized by PCIe in
EEPROM-Less Mode
Problem:
The 82599 without an EEPROM or with a blank EEPROM might not be recognized on some PCIe system
implementations. This issue is not consistent and is unit/board/system sensitive. It is caused because
the hardware default configuration might incorrectly start an internal PLL calibration before the PCIe
reference-clock becomes stable.
Implication:
The 82599 is not recognized by some system implementations.
This issue might cause problems in the manufacturing flow when programming empty EEPROMs, and
also in cases of a corrupted EEPROM failure on a running system.
Workaround:
There are systems on which the 82599 appears less likely to suffer from this issue. In particular for
systems where the PCIe reference clock is stable well before PERST_N is de asserted, the 82599 has a
higher probability of instantiating on the PCIe interface.If possible the most straight forward
workaround for this particular erratum is to ensure a valid and accurate EEPROM image has been
loaded.
Status: B0=Yes; NoFix
27 Device Might Fail to Establish Link When Multiple
Link Numbers Are Advertised by the Upstream
Device
Problem:
The 82599 might fail to establish link when multiple link numbers are advertised by the Upstream
device
Implication:
Successful link might not be established if multiple link numbers are advertised by Upstream device on
a bifurcated port.
Workaround:
None.
Status: B0=Yes; NoFix
