Reboot freeze with autostart amdmemtweak command

I have an Asus Z390-P with 6 x Vega 56.
I am running HiveOS 0.6-203@210403

I enable GUI and then added my straps to the startup with the following:

sudo nano /etc/xdg/openbox/autostart

then added these straps:
/hive/sbin/amdmemtweak --i 2 -–CL 20 --RAS 26 --RCDRD 20 --RCDWR 12 --RC 38 --RP 12 --RRDS 3 --RRDL 5 --RTP 6 --FAW 12 --CWL 8 --WTRS 4 --WTRL 9 --WR 13 --REF 24000 --RFC 239
amdmemtweak --i 0,1,3,4,5 -–CL 20 --RAS 26 --RCDRD 12 --RCDWR 12 --RC 38 --RP 12 --RRDS 3 --RRDL 5 --RTP 6 --FAW 12 --CWL 8 --WTRS 4 --WTRL 9 --WR 13 --REF 24000 --RFC 239 &

I can boot the system and the miner launches with the straps applied. However, if a GPU crashes, the miner will send a reboot command, but the system hangs on a black screen. I will have to power off with the button (one click, not long hold to force power off). When I power back on, straps are applied again and everything is normal.

I have 2 other rigs witht he same command setup and if a card goes down they auto-reboot with no issues. The other rigs are on Biostar MoBo’s.
