thanks @1812 seems like I need to compile my own kernel. Maybe it also works for a custom made unRaid kernel? First of all, I need to educate myself about kernel building

yes I am using a Microserver .. how much of a workaround is that? I am still new to this topic, also doing some reading on IOMMU etc.

After editing config file to: default menu.c32 menu title Lime Technology, Inc. prompt 0 timeout 50 label unRAID OS menu default kernel /bzimage append pcie_acs_override=id:1002:6779,1002:aa98 vfio_iommu_type1.allow_unsafe_interrupts=1 initrd=/bzroot label unRAID OS GUI Mode kernel /bzimage append initrd=/bzroot,/bzroot-gui label unRAID OS Safe Mode (no plugins, no GUI) kernel /bzimage append initrd=/bzroot unraidsafemode label unRAID OS GUI Safe Mode (no plugins) kernel /bzimage append initrd=/bzroot,/bzroot-gui unraidsafemode label Memtest86+ kernel /memtest I got following output: IOMMU group 0: [8086:0158] 00:00.0 Host bridge: Intel Corporation Xeon E3-1200 v2/Ivy Bridge DRAM Controller (rev 09) IOMMU group 1: [8086:0151] 00:01.0 PCI bridge: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor PCI Express Root Port (rev 09) [1002:6779] 07:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
