my current issues are with 3.7 running pppoe in kernel.  It seems that
covad is doing something wonky and resetting my connection throughout
the day.  There is a patch in -CURRENT (soon to be 3.8) that addresses
this issue with the in-kernel pppoe implementation and seems to work
well from what i've heard.  I'm probably going to move to the userland
implementation tonight to see how it goes.
