Do you see messages in kern.log like

Your BIOS doesn't leave a aperture memory hole
Please enable the IOMMU option in the BIOS setup

Either go into the BIOS setup and enable the IOMMU or if your system does not have an IOMMU (too old) try editing /etc/default/grub

adding "iommu=soft swiotlb=131072" to GRUB_CMDLINE_LINUX=""

In my case the diff was

-GRUB_CMDLINE_LINUX="console=ttyS0,9600n8 console=tty0 nomodeset noacpi nosplash nofb"
+GRUB_CMDLINE_LINUX="console=ttyS0,9600n8 console=tty0 nomodeset noacpi nosplash nofb iommu=soft swiotlb=131072"

for an HP Proliant DL145 G2 server

Then run "update-grub" and reboot.
