Description

strange problem that I've seen before, but persists in oi_151a.
after a network powerfail (the computers live on their UPS), when the network comes back
nwam is totally confused. There is network access, but the icons in the right top bar flash every 2 seconds or so between "Wired (nge0) connected", and "Wired (nge0) disconnected"

screen shots supplied.

Strange ifconfig -a output as well...

A reboot seems required as a 'pfexec svcadm restart nwam' doesn't seem to stop it.

What kind of NIC is this, and what is logged in /var/adm/messages when this occurs?

Hi, I've attached an extract of the messages, including a snippet of the lastboot prior to the problem.

The system is an Acer X3200 Nvidia based machine.

Thanks. Looking at that messages file it looks like nwam sees the link come back up and tries to unplumb the nge0 interface, which for some reason fails. Whether nwam is somehow doing that wrong, or whether it's a problem with nge0 isn't clear to me, but after that nwam just keeps retrying and failing till you reboot. I'm assigning this to "OI illumos" since it appears to be a problem with nwam or with the nge driver.

Great, btw, I thought nge was supposed to go MSI:
