>Description:
I have a Dell OptiPlex 740 board.

When cold booting the computer and starting FreeBSD the network is unavailable.

If I cold boot on Windows the network works normally. Rebooting FreeBSD after Windows renders the network available again.

This is a regression wrt 9.0-Release, which booted normally.

I reverted one by one the bge driver changes since 9.0-Release but none of them solved the issue. I suspect the issue is somewhere in the rest of the kerenl, probably in the pci bus.

>Fix:

Another user following -stable on Dell r720 had the exact same problem.

His last comment was: "Well, I've played around with various revisions going back to r234864 to no avail. I'm punting and replacing the BCM5720 with X540Ts for now."
