Impact Solaris 10 systems that have e1000g as the driver for Intel Gigabit 82571EB chipset based NICs may experience Ethernet link flaps. 2. Contributing Factors This issue can occur in the following releases: SPARC Platform * Solaris 10 without patch 128028-03 x86 Platform * Solaris 10 without patch 128029-04 Note: Solaris 8 and Solaris 9 are not impacted by this issue. This issue only impacts systems that are using the e1000g driver for the Intel Gigabit 82571EB chipset based NICs. To determine if a system is equipped with the 82571EB chipset based Intel Gigabit NIC, the following command can be used: $ prtconf -pv | grep "8086,105e" To determine if a system is equipped with e1000g plumbed interfaces, the following command can be used: $ ifconfig -a | grep e1000g 3. Symptoms If the described issue occurs, networking applications may fail due to Ethernet link flaps. In some cases, the link goes down and comes up on its own. However, it is possible for the link to go down and not come back up. In such cases, a manual reboot may be required.
