Same here. There was a new BIOS from Intel for our motherboard (INTEL
S3420GPX), but had another hang last night. Debug below. I will try the
newer driver Monday.
One other thing I noticed is that when the nic is in its hung state, the
WOL option is gone ?
e.g
em1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4>
ether 00:15:17:ed:68:a4
vs
em1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC>
ether 00:15:17:ed:68:a4
Interface is RUNNING and INACTIVE
