Just FYI, I just upgraded a secondary i386 workstation here to
-current last night and am suddenly seeing underruns on the sf card.
Latest one is

sf0: transmit FIFO underrun, new threshold: 208 bytes

The box is pretty much idle - load 0.08, running a zebra bgpd session
with one prefix in table, etc. Dmesg follows.
