I have a DELL 2650 machine that's previously run very well on 2.4 kernels and the bcm5700 driver (chipset is bcm5701, rev15). The interfaces are connected to a 24-port DELL 5224 GigE switch.
I've upgraded to 2.6.0-test9 (plus tg3.c patch contained in bk24 patch)
and am getting what appears to be some sort of autonegotiation problem -- perhaps
related to a flow control problem on the onboard broadcom GigE interface?
The interfaces come up, but I see "Flow control is off for TX and off for
RX", and ping shows packet loss. (See "experiment 1" output
below).
Next I tried disabled autonegotiation on the switch, and explicitly enabled 1000Mbps and flow control. This time it looked like the driver negotiated correctly, but I still get packet loss with ping.
Anything else I can try? Anyone else experiencing problems with the tg3 driver in 2.6.0-test9?
