Denzil Ferreira :fedora:<p>You connect your monitors to a USB-C/Thunderbolt dock, all to then have the screens turn off erratically, or devices connected over USB acting up by turning off at random times? Sounds familiar? You are not alone!</p><p>What if I told that this is because you have not told the kernel that you need IOMMU enabled on your machine? This is particularly true if your monitors also have docks themselves, and the sheer IO overhead is overwhelming your system. How to solve it?</p><p>First, check your device BIOS and see if there is an option to enable IOMMU. Then proceed to enable IOMMU on the kernel:</p><p>For AMD: "amd_iommu=on iommu=pt"<br>For Intel: "intel_iommu=on iommu=pt"</p><p>On Fedora, we use grubby to update our kernel arguments:<br>sudo grubby --args="amd_iommu=on iommu=pt" --update-kernel=ALL</p><p>Reboot and enjoy a much stabler USB, multi-monitor peripherals handling! The reason it's not ON by default is that there is a tiny overhead in memory usage.

Willi<p>hmmm der laptop unterstuetzt kein <a href="https://gruene.social/tags/iommu" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>iommu</span></a> oder <a href="https://gruene.social/tags/xen" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>xen</span></a> unterstuetzt bei dem prozessor noch kein iommu..... das Nas ist immer noch aus, es lag wohl nicht am mainboard... ich kann langsam nicht mehr... ich glaub ich leg mich einfach auf die seite und dass das mit dem computer kram.</p>
