Periodic xl watchdog timeouts on 6.2-RELEASE

I'm trying to track down a watchdog timeout that shows on average once a
day, usually at a random time when idle. The system has two 3c905C NICs
and does ipfw+natd duty with a couple services, and spends most of its
time idle, both CPU and bandwidth-wise. Nothing out of the ordinary
happens when saturating my cable connection at ~8 Mbps, be it with HTTP or
100+ BitTorrent connections. However, I'll randomly see in the logs
during quieter times:
Mar 10 00:04:46 imogen kernel: xl0: watchdog timeout
Mar 10 00:04:46 imogen kernel: xl0: link state changed to DOWN
Mar 10 00:04:48 imogen kernel: xl0: link state changed to UP
It happens on either interface and doesn't cause any problems (so far),
the interface always comes back up. I tried swapping a 3rd 3c905C of a
slightly older revision for one of them, and the messages still showed up
periodically on either. The same hardware ran without any issues or
timeouts on 4.11, and is currently running 6.2-RELEASE plus security
updates. Kernel is GENERIC with a few unneeded items taken out. Onboard
EEPro and sound are disabled in the BIOS. I've also swapped out the
ethernet cables for kicks, no change. Pciconf (cards at the end) and
dmesg are below. Any ideas would be great, thanks.
