>Description:

	I just booted a netbsd-4 kernel from approx 2007/09/02 on a Dell
	PE2650 and have lost ethernet connectivity

bge0 at pci1 dev 6 function 0: Broadcom BCM5701 Gigabit Ethernet
bge0: interrupting at ioapic1 pin 12 (irq 10)
bge0: ASIC BCM5701 B5 (0x0105), Ethernet address 00:06:5b:ed:e2:d1
brgphy0 at bge0 phy 1: BCM5701 1000BASE-T media interface, rev. 0
brgphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, 1000baseT-FDX, auto
bge1 at pci1 dev 8 function 0: Broadcom BCM5701 Gigabit Ethernet
bge1: interrupting at ioapic1 pin 13 (irq 7)
bge1: ASIC BCM5701 B5 (0x0105), Ethernet address 00:06:5b:ed:e2:d2
brgphy1 at bge1 phy 1: BCM5701 1000BASE-T media interface, rev. 0

once# ifconfig bge0
bge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        capabilities=3f00<IP4CSUM_Rx,IP4CSUM_Tx,TCP4CSUM_Rx,TCP4CSUM_Tx,UDP4CSUM_Rx,UDP4CSUM_Tx>
        enabled=3f00<IP4CSUM_Rx,IP4CSUM_Tx,TCP4CSUM_Rx,TCP4CSUM_Tx,UDP4CSUM_Rx,UDP4CSUM_Tx>
        address: 00:06:5b:ed:e2:d1
        media: Ethernet autoselect (100baseTX full-duplex)
        status: active
        inet 204.92.254.13 netmask 0xffffff00 broadcast 204.92.254.255

	Upon "ifconfig up", with *csum_* enable, the driver reports:

once# ifconfig bge0 down
once# ifconfig bge0 up   
bge0: pcistate failed to revert
bge0: RX CPU self-diagnostics failed!


	"ping" works, but UDP and TCP don't -- however disabling all of
	the *csum_* capabilities gets things working again.

	The last kernel with a fully working driver was built 2007/06/29
	from sources updated from the netbsd-4 branch a day or so before.

	I'm guessing one of these is the cause of the problem:
