apport information
** Tags added: apport-collected cosmic
** Description changed:
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.
