freebsd stable - Jul 2009 - [bce] panic on boot in bce(4) on 7.2: invalid ife->ifm_data (0xa)

Hi.

I got the following kernel panic on boot:
invalid ife->ifm_data (0xa) in mii_phy_setmedia

This is near /sys/dev/mii/mii_physubr.c:126
        KASSERT(ife->ifm_data >=0 && ife->ifm_data <
MII_NMEDIA,
            ("invalid ife->ifm_data (0x%x) in mii_phy_setmedia",
            ife->ifm_data));

Kernel is 7.2 GENERIC plus debug options:
options         KDB
options         DDB
options         LOCK_PROFILING
options         INVARIANTS              # Enable calls of extra sanity checking
options         INVARIANT_SUPPORT       # Extra sanity checks of
internal structures, required by INVARIANTS
options         WITNESS                 # Enable checks to detect
deadlocks and cycles
options         DEBUG_LOCKS
options         DEBUG_VFS_LOCKS
options         DIAGNOSTIC
options         BREAK_TO_DEBUGGER
options         STACK

I have no the serial connection on this box this time,
so ddb pictures captured with a camera are here:

Verbose dmesg from stock GENERIC attached.

    device     = 'NetXtreme II BCM5709 Gigabit Ethernet'

I believe that this was because the (un)merged brgphy bits.  Is it
possible for you to use 7.2-STABLE instead?  Otherwise you will need a
patched kernel:

Please make sure that you have a full kernel build.

I see no panic with this patch on 7.2.
Thanks.
