I believe, the messages/behaviour was slowing the system or so, not just giving messages, at least I have seen this on X201T. The workaround is to boot with kernel parameter intel_iommu=igfx_off e.g. set in /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="intel_iommu=igfx_off" and then re-run sudo update-grub and reboot. [I tend to remove "quiet splash" but you could of course have GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_iommu=igfx_off" Playing the Git-Bisect game would be helpful if somebody could find *exactly* where the problem was introduced ...... --Simon
