In day to day practice, there are two reasons for fabsf(airspeed.differential_pressure_filtered_pa) > 15.0f
1/ The sensor has not been calibrated. In this case, the sensor needs to be calibrated.
2/ It's a windy day, and the operator has powered up the system without covering the pitot tube. In that case, you need to reboot with the pitot cover in place.
The original message ('Check calibration') is ok, but why not be more direct? The user does not have to "check the calibration" - the user has to (a) either calibrate the system in the first place, or (b) not forget the pitot tube cover when powering up the system.
Here is the error message:
PX4/Firmware/src/systemcmds/tests/test_matrix.cpp:641:1: internal compiler error: in trunc_int_for_mode, at explow.c:55

problem: previously when connecting power to Power 1, commander refused
to arm (no power source error), and when connecting to Power 2, arming
works, but power consumption was not measured (& shown in QGC).
Swapping Brick1 with Brick2 makes sure both works when connecting to
power 1.
Ideally we will have support for both power sources (including fail-over)
A recent change removed the command forwarding required for VTOL transitions. This change brings this back.

Problem: _mag_device_id is used to get the correct rotation matrix for each
mag. But on POSIX, _mag_device_id was always 0, leading to invalid rotation
matrices.
This resulted in stale mag error messages (rot matrix=0 ==> mag data=0).
_mag_device_id was 0 because there are no /dev/magX devices (eg. on RPi),
thus the mag driver could not be opened.
This patch does: get the device id from the uorb topic instead. We still
need the device handle on certain platforms to apply the calibration params
and to check if the mag is internal or external.
Problem left: on POSIX, the check for external mag does not work.
