Please help troubleshoot/fix.
Xen boot (xl dmesg) will eventually display: `Failed to parse ACPI DMAR. Disabling VT-d). This will disable iommu support.
It’s a Lenovo E15 Gen 2. The BIOS is the latest and I already ran the lenovo critical update to it. BIOS settings are also correct.
It’s strange because I moved the SSD from one laptop to the other and both are exact same model/gen, the only different is the first was ram 8GB, this is 16GB.
I have added to the grub immou=1 and tried other parameters, but they are not doing the trick.
