1. do not upgrade to 6.2.4 (today released), after restart you will see this on COM console:
va not found
Failed to process header
tested on Haswell HW with USB Jun’s Loader v1.04b DS918+ with extra918plus_v0.13.3 and rd.gz + zImage from 6.2.3 .pat file
2. My next test was rd.gz + zImage extracted from 6.2.4 DSM_DS918+_25554.pat file but same error
3. Working test was with rd.gz used from 6.2.4 .pat file + zImage from 6.2.3 .pat file, but half of DSM not works correct.
Please developer to compile new extra (driver extension) version for new 6.2.4.
