>Description:
I have installed a FreeBSD 7.2 (and also FreeBSD 8) on our HP Bl460c G1 Blade system with two Xeon processors and 32 GB RAM. This blade comes with two embedded network controllers and in our case an additionally attached Mezzanine card for two more network controllers. Right after the first boot (GENERIC KERNEL) only the embedded network interfaces get properly configured for use. The additional Broadcom NetXtreme II family NICs of the Mezzanine card (HP NC382m DP 1GbE Multifunction BL-c Adapter) are correctly identified by the bce-driver, but lead to the following kernel debug output:

No PHY found on child MII bus

So the NICs are bound to a logical network card identifier like bce1, but they never become ready to be configured via ifconfig.

$ dmesg | grep bce1
bce1: <HP NC382m DP 1GbE Multifunction BL-c Adapter (C0)> mem 0xfc000000-0xfdffffff irq 18 at device 0.0 on pci16
bce1: /usr/src/sys/dev/bce/if_bce.c(1097): No PHY found on child MII bus!
device_attach: bce1 attach returned 6
