Added to one of the two machines, updated the initramfs (just in case
the module gets loaded in initramfs), and rebooted ... will see if that
works.
The other option I was pointed to was to update to the latest boot
firmware, though I haven't tried that yet:

Troubleshooting
Problem: dmesg is full of smsc95xx 1-1.1:1.0: eth0: kevent 2 may
have been dropped and/or page allocation failure messages:
Solution: Try to update all firmware files in /boot,
especially fixup.dat.
Solution: If the former fails, add smsc95xx.turbo_mode=N to
kernel parameters, or vm.min_free_kbytes=4096 to /etc/sysctl.conf
live well,
