bge0 watchdog timeout -- resetting on 8.2-PREREL never recovers
Just updated a box to the 8.2-PREREL as of friday and now when we do any
serious amounts of network traffice we see:-
bge0: watchdog timeout -- resetting
bge0: link state changed to DOWN
bge0: link state changed to UP
The interface never recovers, we have to use remote console to down, wait
30 seconds then up the interface to restore network access.
This is the details from dmesg:-
bge0: <Broadcom NetXtreme Gigabit Ethernet Controller, ASIC rev. 0x002100>
mem 0xfc9f0000-0xfc9fffff irq 26 at device 5.0 on pci3
bge0: CHIP ID 0x00002100; ASIC REV 0x02; CHIP REV 0x21; PCI-X
miibus0: <MII bus> on bge0
brgphy0: <BCM5704 10/100/1000baseTX PHY> PHY 1 on miibus0
brgphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT,
1000baseT-master, 1000baseT-FDX, 1000baseT-FDX-master, auto,
auto-flow
bge0: Ethernet address: 00:30:48:75:32:42
bge0: [ITHREAD]
pciconf -lbvc:-
bge0@pci0:3:5:0: class=0x020000 card=0x164815d9 chip=0x164814e4 rev=0x10
hdr=0x00
vendor = 'Broadcom Corporation'
device = 'NetXtreme Dual Gigabit Adapter (BCM5704)'
class = network
subclass = ethernet
bar [10] = type Memory, range 64, base 0xfc9f0000, size 65536, enabled
cap 07[40] = PCI-X 64-bit supports 133MHz, 2048 burst read, 1 split
transaction
cap 01[48] = powerspec 2 supports D0 D3 current D0
cap 03[50] = VPD
cap 05[58] = MSI supports 8 messages, 64 bit
Searching around I thought that r216970 might fix this but it looks
like this is already present in another (if_bge.c,v 1.226.2.49)

This may be totally unrelated to bge, investigating a potential failing stick
of ram in the machine in question so until we've ruled this out as the cause
don't want to waste anyone's time.
I did however notice the logic between the two fixes for DMA on 5704's on
PCIX
in svn differ so wondering which ones correct:-
http://svn.freebsd.org/viewvc/base/head/sys/dev/bge/if_bge.c?r1=216085&r2=216970
http://svn.freebsd.org/viewvc/base/head/sys/dev/bge/if_bge.c?r1=217225&r2=217226
r216970 results in:
1, 0, BUS_SPACE_MAXADDR_32BIT, BUS_SPACE_MAXADDR, NULL,
where as r217226 results in:
1, BGE_DMA_BNDRY, BUS_SPACE_MAXADDR_32BIT, BUS_SPACE_MAXADDR, NULL,
