Arc: Workarounds for Loader - AuxXxilium/AuxXxilium GitHub Wiki

First boot

• The first boot after DSM installation can take up to 20 minutes. So stay patient.

Network

• If you don’t get an ip while boot, shut down and power on (not restart) Device. Check for fastboot/silentboot is disabled.
• If you encounter issues with Syno Connection or DSM Installation, disable IPv6 and DoT / DoH.
• If you have an issue that your DSM is not shown in Network: Switch LKM "prod" or "dev" both can work, depends on Hardware.
• If your NIC will not work after booting DSM: Arc Config Mode - Arc Options - DSM Modules - Edit Modules copied to DSM -> Add a new Line above "# kvm" and type "N YOUR_NIC_MODULE.ko" (can be found in Arc Config Mode - Sysinfo) -> TAB to OK and ENTER

Disks

• If your SAS Disks are not detected: Make sure your Disks use 512e or 4kn Blocksize.
• Disks need a unique Serial, this can cause Issues with Raid/SCSI Controller. Best to use HBA and avoid using LSI Logic SAS in Hypervisor.

Disks: Hibernation / HDD Sleep

• Statement from Synology Support to Hdd Hibernation:

We actually recommend turning off hibernation, as the constant sleeping and waking of the drives can cause more wear and tear on the drives, and NAS class or higher drives are designed to run 24/7.

HP Systems

• If you use a HP Microserver with tg3 NIC and the NIC will not work after booting DSM: Arc Config Mode - Arc Options - DSM Modules - Edit Modules copied to DSM -> Add a new Line above # kvm and type N tg3.ko -> TAB to OK and ENTER
• If you have an issue that your DSM is not booting correctly: Set Directboot to "true". (Some HP Systems(Mostly HP Microserver will only work with Directboot.)
• If you use a HP P420i Controller -> https://www.youtube.com/watch?v=JuaezJd4C3I

nVidia GPU

• This should work for the most Systems: https://github.com/pdbear/syno_nvidia_gpu_driver
• Check for working GPU nvidia-smi

SA6400 and i915

• i915 Modules are builtin for up to 13th Gen. So try this first.
• It is possible you need to add a specific cmdline value. Cmdline Menu in Loader for Details.
• If integrated i915 isn't working: https://blog.jim.plus/blog/post/jim/synology-sa6400-with-i915

i915 on other supported Models

• Add i915 Addon
• Check the output of ssh commands: lspci -nnk (Your iGPU should have Device Class [0300] | lsmod look for i915 is loaded | cat /dev/dri there should be some output | dmesg | grep i915
