FreeBSD 7, network dies, console shows: nfe0: tx v2 error 0x6004

[Jim Stapleton]

I got this on a bootup after a power blink.

I had added aio_load="YES" and kqemu="YES" to my loader.conf
beforehand. Removing them + reboot didn't fix the issue.
I switched to the nve driver - no luck, but even fewer useful
diagnostic error messages
I swaped the network cable with a known good, no luck.

Is it safe to assume my onboard nic is toast?
