Broadcom Gigabit Ethernet Slow with Suse 9.3


I am having a problem with the integrated Broadcom 5751 Gigabit ethernet adapter (on ST20G5 Shuttle xPC) . The network is super slow. I tried to ping the router in the network and the response times are really bad in addition to some packets getting lost. I am running SUSE 9.3. After installation the adapter worked just fine, but all the sudden this is what I am getting...

Any ideas how to debug and fix this problem?

Thanks in advance,

any errors in dmesg output? what does mii-tool or ethtool say about the state of the cards configuration?

Here is the output from ethtool. Everything looks good. No HW errors message in the boot log / dmesg. Very puzzled with this.

Started getting these with Ping occasionally in a row, may be a driver buffering problem? And the fight goes on.

ping: sendmsg: no buffer space available.

we had some pretty similar problems with tg3 driven cards at work on a blade array. I'd try forcing the speeds to 1000 full with ethtool, see if that clears anything up, as it's only on 100 at the moment, which i'm guessing isn't what you want? might also want to try using ethereal to grab whatever else might be on that LAN segment.
