ifconfig bge0 resets the device (BETA4)

Hi all,

    I wanted to check some parameters of my bge0 on one of
our Dell PE2650-Boxes, running fresh BETA4. The command "ifconfig" lists
all network devices, works fine. The command "ifconfig bge0" resetted
the interface, the ssh-shell was stalled for a second or two, ifconfig
produced "status: no carrier". The shell is running in a screen 
environment, ifconfig terminated and the interface got up again, shell
is alive.


root_at_pinserv5:~# ifconfig
bge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        options=1a<TXCSUM,VLAN_MTU,VLAN_HWTAGGING>

        ^^^^^^^^^^^^^^^^^^

The logfile:
Sep 16 15:58:46 pinserv5 kernel: bge0: gigabit link up


Same thing on a similar box (PE2650, BETA4) without screen:

root_at_pinserv4:~# dmesg | grep bge0  ; ifconfig bge0
bge0: <Broadcom BCM5703 Gigabit Ethernet, ASIC rev. 0x1002> mem 0xfcf10000-0xfcf1ffff irq 28 at device 6.0 on pci3

        inet 10.101.240.54 netmask 0xffffff00 broadcast 10.101.240.255

Another one, with screen:
root_at_pinserv6:~# ifconfig bge0
bge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        options=1a<TXCSUM,VLAN_MTU,VLAN_HWTAGGING>

    <-- stalled here -->
        inet6 fe80::20d:56ff:febb:9c27%bge0 prefixlen 64 scopeid 0x1

        media: Ethernet autoselect (1000baseTX <full-duplex>)
        status: active
        ^^^^^^^^^^^^^^

Whats wrong?
