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
Bug#962003: *ERROR* Failed to wait for idle; VT'd may hang
Hi. I just installed Debian bullseye daily today (linux-image-amd64 version 5.10.40-1), and ran into this problem on a Lenovo X201. The message repeats every other second or so. I don't notice any other problem except for the repeated messages, fortunately. I have tried installing the non-free intel iucode and 915 firmware packages (intel-microcode and firmware-misc-nonfree), but they don't appear to make a difference. /Simon Jul 17 15:59:44 latte kernel: [ 2612.027659] i915 :00:02.0: [drm] *ERROR* Failed to wait for idle; VT'd may hang.
