Anyone seen this error on em ?

[gnn at freebsd.org]

Jun  9 18:23:59 ... kernel: em0: <Intel(R) PRO/1000 Network Connection
Version - 6.7.3> port 0x2000-0x201f mem 0xd8020000-0xd803ffff,0xd800
0000-0xd801ffff irq 18 at device 0.0 on pci4

Jun  9 18:23:59 ... kernel: em0: Setup of Shared code failed

I've never seen the "returned 6" thing.  Plugging a cable into the
other em device on the motherboard, a super micro, currently works,
but it looks like bad hardware to me.  Thoughts?

Later,
