My apologies for the extended delay in responding. I ended up getting Click 1.0.2 to compile with some modifications, but get kernel crashes at install with some regularity. As best I can tell, the crashes are actually caused by the igb driver, not Click. If Click installs and doesn't crash within the first 5 seconds, it stays rock solid.
Next time I need to restart Click on this server, I'll see if the latest repository works for me. As for the memory issue, I have always had to run strip -g on the click.ko file in order to get it to install. -- KS On Fri, Mar 1, 2013 at 10:47 PM, Eddie Kohler <ekoh...@gmail.com> wrote: > Hi Keith, > > I got a look at this.
