Last time this machine was updated was last week.
I'm going to have to install something else to test the hardware, but it
had no problems until first reboot with new kernel.
I have blown away /usr/src and re fetched it...no change.
I've disabled pf and tried to bring it up...no change
I've tried to bring up the other interface in the pair...no change (igb1).
It doesn't look like the msix commit from jhb has anything to do with
it...didn't exactly revert but changed return(0); back to
I'm down to either the hardware conveniently failed during upgrade, or
some earlier commit.
Luckily I have an em-based port as well.
I'm testing hardware next and then going further back into the week on
the commit log?
Anyone else with igb out there and working with latest HEAD?
