Here's my workaround, it was disabling IOMMU On Debian 12, 13 and Ubuntu 24.04 (and likely all other Debian/Ubuntu- based systems), my laptop freezes temporarily when the power cord is plugged in. This appears to be caused by IOMMU (VT-d) misbehaving during power state transitions. So the solution is:
Edit /etc/default/grub and add "intel_iommu=off" to the end: "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_iommu=off" And run: sudo update-grub sudo reboot -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2061840 Title: Ubuntu 24.04 freezes after plug in power cable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2061840/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
