More precisely the board is a "Marvell Armada XP Development Board
DB-MV784MP-GP"

I have started a "bisection" with the kernels from snapshot. This is
what I have found so far:
This one works:
- linux-image-4.19.0-rc6-armmp-lpae_4.19~rc6-1~exp1_armhf.deb
The following ones don't:
- linux-image-4.19.0-rc7-armmp-lpae_4.19~rc7-1~exp1_armhf.deb
- linux-image-5.0.0-trunk-armmp_5.0.2-1~exp1_armhf.deb
My guess (I don't have time to try more now) is that the issue is caused
by the following change:
| [ Uwe Kleine-König ]
| * [armhf] enable MVNETA_BM_ENABLE and CAN_FLEXCAN as a module
Add Uwe as Cc: so that he can comment on the change.
