Yes, i tried, but have no effect.

What about other NIC chips from Broadcom? And how about the packets other
than icmp under the same load?

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

bge0@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,

Jeff
