[Click] Kernel and Intel Driver Versions and Click Patches

Tom,

This is the e1000e driver that Joonwoo released.  When you use it, you
need to use PollDevice instead of FromDevice Click elements.  As far as
crashes go, it would help to see the dmesg output when the crash
happens.  You might be able to see the messages in /var/log/messages
even after the reboot.  The other way is to use a serial console.
