>Description:
The bge(4) driver stopped working correctly with some 1000SX (fiber cards) then 
going from NetBSD 4.0.1 -> NetBSD 5.0 BETA

NetBSD 5.0 BETA output (Dell 2650 + extra interface cards):

wilma# grep bge2 /var/run/dmesg.boot:
bge2 at pci5 dev 6 function 0: Broadcom BCM5701 Gigabit Ethernet
bge2: interrupting at ioapic1 pin 8 (irq 10)
bge2: ASIC BCM5701 B5 (0x0105), Ethernet address 00:0a:5e:01:06:28

wilma# ifconfig bge2

NetBSD 4.0.1 output (an almost identical machine):

$ grep bge2 /var/run/dmesg.boot
bge2 at pci4 dev 8 function 0: Broadcom BCM5701 Gigabit Ethernet
bge2: interrupting at ioapic1 pin 4 (irq 10)
bge2: ASIC BCM5701 B5 (0x0105), Ethernet address 00:04:76:f8:e9:63

$ ifconfig bge2
bge2: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
        
capabilities=3f00<IP4CSUM_Rx,IP4CSUM_Tx,TCP4CSUM_Rx,TCP4CSUM_Tx,UDP4CSUM_Rx,UDP4CSUM_Tx>
        enabled=0
        address: 00:04:76:f8:e9:63
        media: Ethernet autoselect (1000baseSX full-duplex)
        status: no carrier
>How-To-Repeat:
Under NetBSD 5.0 BETA:

wilma# ifconfig bge2 inet 130.242.82.186 netmask 0xfffffffc
bge2: block failed to stop: reg 0x3400, bit 0x00000002
bge2: block failed to stop: reg 0x2400, bit 0x00000002
ifconfig: SIOCAIFADDR: Invalid argument

Under NetBSD 4.0.1:

dino# ifconfig bge2 inet 10.0.0.1 netmask 0xfffffffc
dino#
