Thank you for providing the test kernel. I am afraid this does not resolve the issue.
As mentioned in the upstream bug report, it turned out that the problem is triggered in the xhci-pci code and caused by an ExpressCard Renesas uPD720202 USB 3.0 controller. I was able to narrowed the issue down to commit 0e1f0ea which forces a PCI reset on that device at startup and have reported the problem to the linux usb mailing list: https://marc.info/?t=150565318600001&r=1&w=2 It looks like the reset leaves the controller in an unstable state, triggering - pipe A vblank wait timed out and - pipe B vblank wait timed out kernel messages. On my machine reverting the mentioned commit reliably resolves the issue for kernel versions 4.12.8, 4.13.1 and 4.13.2. The same is true for removing the external ExpressCard. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1716747 Title: linux 4.12 - high system load and mouse delays - pipe A vblank wait timed out Status in linux package in Ubuntu: In Progress Status in linux source package in Artful: In Progress Bug description: This issue has been observed on a Lenovo X220i laptop: 1. Booting the laptop with artful's 4.12 kernel results in a very sluggish system performance (mouse pointer delays) and a high system load. 2. /var/log/kern.log indicates a problem with the display driver (see below) 3. The system works without any issues if the zesty kernel (4.10) is used instead.
