Bisecting is a manual process, since it's some option (or combination thereof) enabled in Fedora's .config that's the problem rather than a bad commit which git can help with.
You're right in that it's not drm-tip itself. In fact, while the original weirdness manifested itself in drm, it also trashed the disk controller. In the last couple stock fedora kernels (5.1.6 and 5.1.8), the problem has shifted to the keyboard controller (or maye it's usb, haven't disentabled it). So something in there is stomping on things it shouldn't, and for the longest time, that was the video driver. Since I'm now pretty certain it's not your bug, closing this one is fine: I'll keep poking at it till I solve it, or until I finally upgrade this T430, whichever comes first :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1751268 Title: bionic desktop does not boot with external monitor attached - [drm:ironlake_crtc_enable [i915]] *ERROR* mode set failed: pipe A stuck / vblank wait timed out on crtc 1 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1751268/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
