Greetings, I have been receiving these messages on a recent 8.1/AMD64 install. src/ports && world/kern about a week ago. Here is a block from the most recent output: nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> nfe0: tx v2 error 0x6204<UNDERFLOW> It appears to only occur when transmitting largish amounts of data across an NFS mount. I'm not sure where the MIN-threshold lies. But appears to be >=1.5Mb. This fresh 8.1/AMD64 is part of a largish server farm comprised of 7+ - 8.0 i386 servers. This one is the only AMD64. It is also the only AMD64. I experience this when mounting an 8.0/i386 server from this 8.1/AMD64. The i386 also has mounts on this 8.1/AMD64. relevant info: ### 8.0/i386 8.0-STABLE FreeBSD 8.0-STABLE #0: /usr/obj/usr/src/sys/UDNS01 i386 Tyan 2-CPU MB 2 NIC's: fxp0 (only one in use) ### 8.1/AMD64 FreeBSD 8.1-RELEASE-p2 #0: /usr/obj/usr/src/sys/XII amd64 MSI K9N4 Ultra CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ (3511.34-MHz K8-class CPU) 1 NIC nfe0 ### common to both: rc.conf nfs_client_enable="YES" nfs_reserved_port_only="YES" nfs_server_enable="YES" NIC's on both boards are 10/100's @100mbps Can anyone provide any insight as to why I should be receiving these messages on a fresh 8.1/amd64 install. Is 8.1 INcompatible with earlier versions? Thank you for all your time and consideration. --Chris
