Thanks for getting those logs. Unfortunately I'm still not able to
reproduce the problem.

The logs show that the data which triggers the panic is read from a
pipe, but the problem happens on the other side, before or when the data
enters the pipe. I've been looking at code and haven't identified the
cause so far, though there's still more code to investigate.

While I'm doing that it would be helpful if you could reproduce the
problem again with the test kernel below. This should tell us where the
problematic data comes from. I also added some printouts to provide
additional information at the point where the panic occurs. Hopefully
this gets us to the root cause and not to another layer of indirection.

Title:
  Kernel panic

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I run ubuntu servers 13.04 and 13.10 on the AWS cloud. Whenever I
  install haproxy and nginx on the same server, after hitting it for a
  while, a kernel panic is caused. However, the kernel panic does not
  show up in ubuntu 12.04.  The kernel panic is pasted at the end of the
  attachment.
