Most of my machines are ESXi 5.1 VM's running the e1000 (em0) NIC.

Most often the systems stay functional, they just need a reboot or more mbufs if I add them. Some times they lock up or crash as I ifconfig down/up the adapter or attempt to add more mbufs via sysctl. > > 1) Is anyone else able to reproduce this problem?

It's not just my systems, as evidenced by the original poster of the PR. 1. This PR does not contain output from "dmesg" nor "pciconf -lvbc", nor does your Email. Output from this matters. 2. Please try 9.1-STABLE and see if there is an improvement; there have been a huge number of changes/fixes to em(4) between 9.1-RELEASE and now.
