I am still seeing this issues with 4.13.0-16. Ultimately this problem (at least in my case) seems to be a PCI express power management issue (see https://www.spinics.net/lists/linux-pci/msg64778.html).
The following workarounds solve the problem on my system: a) remove the PCI express card from the system, or b) disable the PCI express power management in the Lenovo X220i's BIOS Another option is to use a kernel that reverts commit 8466489ef5ba48272ba4fa4ea9f8f403306de4c7, although the correct solution would be to investigate and fix the power management issues which trigger this problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1716747 Title: linux 4.12 - high system load and mouse delays - pipe A vblank wait timed out To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1716747/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
