(previously posted on freebsd-questions, but with no resolution) I get this error quite frequently on my pf firewall running 6.2 and it leads to loss of internet access. kernel: vr0: discard oversize frame (ether type 710a flags 3 len 1532 > max 1514) vr0 is connected to my ISPs cable modem, ip address is provided by DHCP. Whenever I get this oversized (or maybe malformed) packet I need to reboot my machine to get back online, though sometimes just resetting (down, then up) the ethernet port works also. I get the same problem with rl network cards (previously reported by Jeremy Tay: "misc/63190: Realtek driver halts on oversized frame" , FreeBSD 5.1-RELEASE , http://lists.freebsd.org/pipermail/freebsd-bugs/2004-February/005534.html ) Reports with other ethernet cards: xl http://angel.kafazov.com/blog/?p=41 FreeBSD 6.1 sk : http://lists.freebsd.org/pipermail/freebsd-bugs/2004-September/008784.html 6.0 kern/71229 sis: http://lists.soekris.com/pipermail/soekris-tech/2006-January/009829.html 6.0 bge : http://www.mail-archive.com/freebsd-net@freebsd.org/msg21324.html sai
