Once in a while an error occurs during system startup:
*** Error in mount_flash: mount_part: Unknown filesystem ***
### Starting debugging shell for boot step: mount_flash... type exit to quit ###
When the device is connected to the TV, the error is manifested by a black screen.
When the device is connected to a monitor you can read the error.
On shutdown:
Failed to unmount /flash: device or resource busy
systemd-shutdown[1]: Failed to finalize file systems, loop devices, ignoring.
Device: Intel NUC7i5BNH
Disk1: HDD 1TB
Disk2: mSata - boot disk
The same problem occurs in the latest nightly.
Before the update, there were no startup issues.
