Comment 2 Neil Horman 2007-08-08 15:29:57 UTC 
hmmm, looks like we tried to copy data beyond the length of the allocated
buffer.  First, question would be, have you tried with the 4.6 kernel, e1000 has
had several complete updates.  Also, can you try adding the copybreak=0 option
to the module, and see if that clears the problem up.  Thanks!

It looks like you didn't turn off copybreak in your last test.  Please do so and
report results.  Thanks!

No crashes any more, close it...
