[Solved] AMD/unRaid kernel: print_req_error: I/O error, dev nvme0n1

Greetings,

I was reviewing the VT video and article about IO issues with TRIM and AMD titled Devops Workstation: Fixing NVMe Trim on Linux

Being new to this, where would the iommu=pt avic=1 command go on an unRaid system?

Thanks

Tools > Config File Editor > /boot/syslinux/syslinux.cfg

You add the parameters to the append line.

Thanks…

I currently have:

append initrd=/bzroot acpi_enforce_resources=lax

Does it matter where iommu=pt avic=1 is added on this line?

Thanks again

I don’t know but I don’t think it would matter.

I did append initrd=/bzroot iommu=pt avic=1 acpi_enforce_resources=lax and it worked!

Thanks again.
