I started seeing computer lockups with kernel 4.13.0 reporting a "fifo underrun on pipe B" when a multiple monitor setup enters power save state. It's nearly 100% reproducible. No issues with just the laptop screen, without an external monitor.
I've just upgraded to 17.10. As 4.13.2 is reported to resolve some issues above, is is on the way to the distros? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1550779 Title: [i915]] *ERROR* CPU pipe A FIFO underrun - Xorg glitches To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1550779/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
