Hi Peter, We have some ideas and are working on a patch for you to try. Since we won't really be able to test it can you do that if we get it to you? Do you know how to patch a driver? Or should we send you the whole thing (a complete new driver like you would get off of our SF site)? Chee

Module parameters aren't well-liked in the kernel and they won't let them into the code. Sourceforge is a different matter. You can get the same setting using ethtool -C rx-usecs 0. On Thu, 6 Jun 2013, Don Smith wrote: > Here is the relevant information. Help understanding why this does not > wo

OK so a couple of thing kind of stand out. What interface is the e1000 on? eth0? That's not being called out or you filtered it out from the dmesg. Early on eth2 is the e1000 interface but later it's one of the Gianfar interfaces. Can you clear this up for us? Also, it looks like you have a

Here is the relevant information. Help understanding why this does not work according to the README file description for 3.2.10 will be greatly appreciated. The driver module was installed with the distribution, not built from the code on Sourceforge. Thank you. -- Don Smith ===

I agree with Jesse but this driver has been in the field for a very long time with no reports like this coming to us. Can you send us the dmesg when this is happening? I want to see if there are messages from the driver like if the down is being delayed somehow. Or re-enabled. Thanks. Cheer
