4.3-STABLE about two weeks old.

I recently aquired a second CPU for a server and when the
box runs a SMP kernel the ethernet exhibits packet loss from
what appears to be transmit framing errors.  With a single
CPU it runs just fine.

It's an older LX based Tyan Tomcat, the NIC is a Kingston,
I think:

dc0: <82c169 PNIC 10/100BaseTX> port 0xe800-0xe8ff mem 0xfebfef00-0xfebfefff irq 11 at devic
e 11.0 on pci0
dc0: Ethernet address: 00:c0:f0:5b:4c:5f
miibus0: <MII bus> on dc0
ukphy0: <Generic IEEE 802.3u media interface> on miibus0
ukphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

I'm not positive that the two CPUs are the same stepping but 
the box does boot just fine and exhibits no other strange
behavior -- the console is responsive and there are no 
errors in dmesg.  Seems to me that if the chips weren't happy
I'd see other errors.

Any Ideas? Is the dc driver broke under SMP?
