Results with mainline kernels: * linux-image-unsigned-4.18.20-041820-generic: bug present, same behaviour as in linux-image-4.18.0-14-generic * linux-image-unsigned-4.20.7-042007-generic: bug fixed!
One other interesting factoid: after the failed modeset, the system isn't _completely_ dead. I can type in my passphrase for my encrypted partition, and after another 10-12 s (the usual delay) the system is ping'able and ssh'able. So stuff is up and running. But here's what does not work: * software reboot from console (Ctrl-Alt-F1, then Ctrl-Alt-Del) * "sudo reboot" from ssh session * "sudo poweroff" from ssh session The only ways I can regain control are the PC reset button or hardware power off. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1815152 Title: kernel hangs on boot after "fb: switching to inteldrmfb from VESA VGA" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/1815152/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
