Have you found a solution to this? I am having the same problems on a
machine very recently updated (cvsupped + buildworld on 4/14/2005):
kernel.log:Feb 25 13:46:40 trinity kernel: rl0: discard oversize frame
(ether type 3db4 flags 3 len 8381 > max 1514)
kernel.log:Apr 10 14:27:37 trinity kernel: rl0: discard oversize frame
(ether type 5a84 flags 3 len 2614 > max 1514)
kernel.log:Apr 18 16:17:53 trinity kernel: rl0: discard oversize frame
(ether type 1867 flags 3 len 16941 > max 1514)
After the message, the machine becomes completely unresponsive and I
have to do a power-off, power-on reset.
