I was unable to get a coredump.  Entering 'panic' at the db> prompt
did not provide me with a core dump neither did 'call dodump'.
After syncing with today's HEAD I don't get the panic, though the
re(4) interface comes up I cannot pass data on the connection.
I have posted[1] the latest dmesg, pciconf, ifconfig and a tcpdump from
the laptop as it tries to ping my desktop using the re(4) interface.
The MAC addresses appear to be shifted the same as the first laptop as
I reported on IRC.

Yes, on dfly aue(4) operates at 10UTP on freebsd it operates at 100TX.
I can force the interface to 100baseTX full-duplex and it works but
slightly slower than 10UTP.
mmm, can you show me the dmesg of FreeBSD6, especially the aue related
line to aue(4)?  Thanks.  It is probably because FreeBSD6 still uses
ukphy for your aue(4).

After syncing with HEAD the problem remains.

It looks like alignment problem here, the whole arp packet is shifted
by 2bytes (should be ETHER_ALIGN):
