[Elecraft] Firmware failed to load, again

[DM4iM]

Elecrafters,
when updating to 4.22 , DSP1 again failed to load.
DSP1 is skipped, the Utility proceeds with DSP2.

I need to start a second run with only DSP1 checked
to complete the update.
This happened with 4.17, 4.18 and 4.22.

Otherwise the radio works 'as advertised'

I installed the K3DSPLPF recently.

Anyone experience this?

Radio is K3 # 2878
SUB RX

Utility is the latest Linux version.
Real serial connection (ttyS0), no USB.
