description |
A few days ago, I let update-manager upgrade my kernel from 4.18.0-13 to 4.18.0-14. Since then, my system is unable to boot. It freezes after printing
fb: switching to inteldrmfb from VESA VGA
but before it gets around to asking me the passphrase for my encrypted main partition. (At first I thought it was a problem with cryptsetup because it never got to that prompt, but now I'm pretty sure it's something to do with changing video mode.)
However, if I use the grub menu to select the older 4.18.0-13, the system boots just fine. It looks very much like a bug introduced between 4.18.0-13 and 4.18.0-14.
Additionally, if I boot 4.18.0-14 in maintenance mode, the kernel modesetting does not happen, and the system boots just fine. (Except for the 1980s-style low-res video, that is.) This seems like good evidence that it's a problem with setting the video mode.
I'll test with some mainline builds, but I want to get this bug report opened before I start rebooting. |
