[Bug 563267] [NEW] system hang & kernel oops e1000e driver null pointer in transmit cleanup

[Charles]

Public bug reported:

I have been experiencing a number of system hangs which I believe are
due to the e1000e driver. I have a Dell Optiplex 760, Intel Core 2 Duo,
4GB RAM, and I'm running Ubuntu 9.10 (32-bit).

>From the stack included in the kernel oops output, I decided to apply
the patch you provided, which I found posted here:

    http://patchwork.ozlabs.org/patch/49175/

The line numbers did were off by 5 lines, but I inserted the lines in
the proper place. I have been using the patched e1000e.ko module for
less than a week.

This morning, I attempted an rsync operation which caused a hang once
again.
