Hi to all ! There's a problem in firmware for Broadcom NIC BNX2X after update Proxmox to 1.6 release. The k.module BNX2X search firmware bnx2x-e1h-5.0.21, not present /lib/firmware. I've just found this BIN in a release on Debian Squeeze, copy the BIN and Proxmox 1.6 works correctly on Broadcom 10gbit NIC. Happy Proxmox :) Luca
