[Adam Conrad]

Hello dann, or anyone else affected,

Accepted flash-kernel into trusty-proposed. The package will build now
and be available at http://launchpad.net/ubuntu/+source/flash-
kernel/3.0~rc.4ubuntu49.4 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Title:
  console speed on HP Moonshot platforms may vary

Status in “flash-kernel” package in Ubuntu:
  New
Status in “flash-kernel” source package in Trusty:
  Fix Committed

Bug description:
  [Impact]
  The serial console on HP Moonshot cartridges is connected to the chassis manager which currently expects data at 9600 baud. We are therefore hardcoding a kernel commandline argument of console=ttyS0,9600n8r. However, it is possible for this baud rate to change in the future. Using the firmware-controlled ${baudrate} setting instead of hardcoding the rate will allow us to adjust to such changes dynamically. Of course, it isn't a full solution (getty needs to be dynamic as well), but is required.
  [Test Case]
  Use test firmware from HP to bump the firmware from 9600 to 115200 and verify that the console output is still visible over the VSP (virtual serial port).
  [Regression Risk]
  It's easy to test that working combinations still work today.
