    Yes 00:01.0
    There is modified script just for this one:

    Before:


    So i managed to get this:
    obraz.thumb.png.cb7f532f0a073f1640c02b597433eece.png

     

    00:01.0 now have ASPM Enabled using https://gist.github.com/baybal/b499fc5811a7073df0c03ab8da4be904 

    Still getting only to C3...
    In this post https://libreddit.proxy.vrozaksen.eu/r/homelab/comments/130ly7h/cant_achieve_lower_cstates_stuck_at_c3_despite/

    OP says his issue was on-board network card and AsRock Z390m-itx/ac uses 2 different on-board LAN cards. I211 and I219.
    Maybe one of those cards generates this issue? I can't test that right now, but maybe u got any information about those cards.

    Hi! So i'm using AsRock Z390m-itx/ac.
    For last 2 hours i was trying to reach higher than C3 state, but with no luck.
    Every C-State enabled.

    Every ASPM enabled (first L1 then L0sL1, no difference)
    Audio disabled.

    No pci-e devices. Only ASM1166 on M.2 slot.

    Other parts:
    MOBO: AsRock Z390m-itx/ac
    CPU: i5-9400
    PSU: Corsair RM550x (2018)
    RAM: 2x Corsair Vengeance LPX, DDR4, 8 GB, 3000MHz, CL16

    I was testing with stopped array.
    My go file:

    EDIT: After reboot with array started i get 0% everywhere.

    Is my drive dead?

    in General Support

    Posted · Edited by Vrozaksen

    Okay after "rebuild" it was good and yesterday it happend again. Using different cables didn't help. Maybe there is HDD connector issue? I bent it little bit to much couple month ago, but everything was looking good. I scratch my head what the issue.

    @Michael_P HDD shows CRC errors, SMART doesn't show anything special. It's still the same drive on different cables.

    Help with my Seedbox / Sonarr / Syncthing setup

    in General Support

    Posted · Edited by Vrozaksen

    @up that's what I have setup, this work really good, but then i have to check what Sonarr/Radarr imported, then i can delete it on seedbox manually... I'm looking for script or tool for rTorrent/Syncthing which will delete files on seedbox after successful import to Radarr/Sonarr

     

    Edit:

    I think it's better to use Deluge in this case, i will test it later

    Edit:2

     

    Soo i recommend Transmission (Deluge have crashing problem), everything works great!
