Problems with bge (possibly related to r208993)

[Artem Kim]

Hi,

I have two routers (HP DL140G3):

NAS3 FreeBSD 8.1-PRERELEASE # 0: Thu Jun 3 04:13:07 MSD 2010 i386
NAS2 FreeBSD 8.1-PRERELEASE # 0: Sat Jun 12 16:42:19 UTC 2010 i386 (r208993 
included)

bge0 @ pci0: 19:0:0: class = 0x020000 card = 0x3260103c chip = 0x165914e4 rev 
= 0x11 hdr = 0x00
    vendor = 'Broadcom Corporation'
    device = 'NetXtreme Gigabit Ethernet PCI Express (BCM5721)'
    class = network
    subclass = ethernet
bge1 @ pci0: 20:0:0: class = 0x020000 card = 0x3260103c chip = 0x165914e4 rev 
= 0x11 hdr = 0x00
    vendor = 'Broadcom Corporation'
    device = 'NetXtreme Gigabit Ethernet PCI Express (BCM5721)'
    class = network
    subclass = ethernet


I have some problems with bge on NAS2.

After some time (about 15 hours) bge1 stops flowing traffic.
NAS3 NAS3 - pppoe server. Through bge1 passes only ip traffic through bge0 no 
ip-traffic.
Problems occur only with the bge1 interface on NAS2.


Traffic through bge1 not pass until I will not do "ifconfig bge1 down ifconfig 
bge1 up".

When I do "ifconfig bge0 down" NIC does not shutdown:

nas2 # ifconfig bge1 down
nas2 #
nas2 # ifconfig bge1
bge1: flags = 8843 <UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options = 8009b 
<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,LINKSTATE>
        ether XXXXXXXXXXXXX
        inet YYYYYYYYYYY netmask 0xffffffc0 broadcast YYYYYYYYYYYY
        media: Ethernet autoselect (1000baseT <full-duplex>)
        status: active
  
LED also indicates that the NIC is active.

I left the NAS in a state of "frozen bge1" - and can provide additional 
information for diagnosis.
