I have been unable to produce time outs with my current setup in 
6.2-Release.

bge0 at pci3:0:0:  class=0x020000 card=0x81491043 chip=0x165914e4 rev=0x11 
hdr=0x00
     vendor   = 'Broadcom Corporation'
     device   = 'BCM5750A1 NetXtreme Gigabit Ethernet PCI Express'
     class    = network
     subclass = ethernet

Reading the PR, I attempted triggering this through CVSing and through 
the above mentioned ping tests.

So far nothing.

The only issue I have seen using these NICs in 6.2R is if I nail up the 
NIC at 100baseTX full-duplex I sometimes loose connectivity.   Nothing 
in the logs indicate watchdog timeouts or any other issue.   I simply 
brought the NIC back down to auto-neg and all seems fine.   I am 
assuming this is a incompatibility between the BGE and my switch, RS8000.

I have a Asus P5MT-S with dual BGE NIC's

Cheers,
