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. -Kyle David Malone wrote: >On Fri, Feb 25, 2005 at 10:00:34AM -0500, Jonathan Pater wrote: > > >>fxp0: discard oversize frame (ether type 800 flags 3 len 1515 > max >>1514) >> >>Is this something I should be >>worried about, or is it indicative of something else faulty in the local >>network setup? >> >> > >This message is produced if the ethernet card receives a packet >that is bigger than permitted by the MTU + the size of the ethernet >header.
