Thanks. I see that someone else found a similar problem with the igb drivers
back in March, but they decided to fix it by just shortening the udelay
interval to 10000us instead: http://www.spinics.net/lists/netdev/msg233769.html
It looks like that change has already been submitted to the mainline kernel;
I'm not sure which approach is best.

Sure, attached. (You may have to build with gcc -O3 to repro the error.)
