tg3 driver timeout problems
Subsystems (2)
Hi,
we're experiencing serious problems on an productions system running fecora core5 ( 2.6.17-1.2157_FC5smp #1) and
running the tg3 driver.
Here is my dmesg output:

The sympton is that sometimes the network is down we cant ping the network device anymore.
Also from a shell we cant ping the outside world. We can still ping the ipnr of the network device itself.
A restart of the network using /etc/init.d/network restart does the trick and the device works again.
I dont think this is related to the TSO problem reported earlier because I believe its disabled by default.
Any clues, help would be appreciated.
Please let me know if I need to provide additional debug info.
thanks,regards

TSO may be on by default on eth0 where you have a 5721. Check with ethtool -k eth0. Turn it off if it is on by doing ethtool -K eth0 tso off.
Thanks a lot Michael, it seems to have resolved the issue, at least we were not able to reproduce it again
after changing this flag. I will update this thread if the issue reoccurs.

That's good to know. When you upgrade to the next 2.6.18 kernel, you can re-enable TSO because the latest driver has the workaround for this problem.
