tftpd - timeouts and possible Denial-Of-Service

em driver problem on vmware

Howdy, I have freebsd80-release with an upgraded em0 driver from freebsd8.1 (and an appropriate touch of if_var.h). I'm running an amd64 on a vmware vm. And I see this in dmesg: cut- em0: port 0x2000-203f mem 0xd894-0xd895, 0xd890-0xd890 irq 18
