Bug#347412: Sorry it took so long, tested sk98lin
Same problem. Network died.
I did notice that udev/discover were somehow loading both the skge and
sk98lin modules. The sk98lin test I just did was after confirming that
skge had never been loaded since boot.
I can test again with only skge loaded since boot, but it can take some
time to reproduce the problem.
(e.g., massive 50mbps ping flood combined with 75MB/sec of IO did not do
it after 10 minutes or so. But reading gmail in firefox did, after an
hour or so.)
