8.0-beta freeze when bringing up bge0 on certain HP Proliant servers

Hi

Setting bge0 to UP causes a freeze on these HP Proliant models:
DL380 G4
DL360 G4p
I suspect DL380 G4p and DL360 G4 are affected as well, since they're 
essentially the same, but I can't confirm that.

These servers have onboard dual Broadcom NetXtreme Dual Gigabit Adapters 
(BCM5704), but the problem only occurs on bge0, not bge1. I found no 
difference between having a cable plugged in or not. I have tested 
beta1, beta2 and -current as of today.

 From pciconf -lv

bge0_at_pci0:3:1:0:        class=0x020000 card=0x00d00e11 chip=0x164814e4 
rev=0x10 hdr=0x00
    vendor     = 'Broadcom Corporation'
    device     = 'NetXtreme Dual Gigabit Adapter (BCM5704)'
    class      = network
    subclass   = ethernet
bge1_at_pci0:3:1:1:        class=0x020000 card=0x00d00e11 chip=0x164814e4 
rev=0x10 hdr=0x00
    vendor     = 'Broadcom Corporation'
    device     = 'NetXtreme Dual Gigabit Adapter (BCM5704)'
    class      = network
    subclass   = ethernet

 From ifconfig (interesting that media on bge0 doesn't say "(none)" as 
it usually does.)

bge0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
    options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM>

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

 From dmesg

I hope someone can look into the problem. I can dedicate this box for 
testing for a while.
