Title:
  Ubuntu-4.6.0-5.6 configuration has CONFIG_GOLDFISH and
  CONFIG_GOLDFISH_BUS enabled, breaking serial support on normal systems

Status in linux package in Ubuntu:
  In Progress

Bug description:
  When CONFIG_GOLDFISH_BUS is set to "y", the goldfish_pdev_bus driver
  is compiled into the kernel and claims the serial UART, breaking
  serial communications with the following kernel message: "genirq:
  Flags mismatch irq 4. 00000000 (serial) vs. 00000080
  (goldfish_pdev_bus)" repeated several times on boot.

  I checked the configs for 4.4 in Yakkety and Xenial and 4.5 in
  mainline and found that CONFIG_GOLDFISH was set to "n" there,
  completely disabling all the goldfish drivers.  Since this is a driver
  for the Android emulator, I'm not even sure it is appropriate to be
  enabled at all for desktop systems, but the goldfish_pdev_bus driver
  breaking serial definitely shouldn't happen.
