Using the 6.0-CURRENT June 2nd Snapshot, I get a panic pretty quickly
when using an original NForce 1 MCP Network Card(new nve driver). This
has happened while I was running sysinstall via pxeboot, and starting a
ftp install. This is what I copied from the screen, omitting some
things later in the stack trace:
anic: nve_ifstart: attempted use of a free mbuf!
cpuid = 0

swi_net(0)
....
I don't have the gear locally to setup a serial console, so I am hoping
this is enough to give someone a clue. It looks easy to reproduce, and
I am happy to provide more information if needed.
I did find a mention of a similar panic back in October of 2004, but it
was for the fxp driver:
