Running Ubuntu on a Zenbook Pro 14 UX480FD. Its been working okay for the past months but since running sudo apt update && sudo apt upgrade
just earlier the other day, it's stopped booting correctly. GRUB loads fine but booting to any linux distro freezes after Loading initial ramdisk...
. Recovery doesn't work either, but booting to an install USB works. fsck finds nothing wrong, no updates available after running chroot from install USB. Reinstalling is possible to do but the problem reoccurs when running upgrade (on a fresh system!).
I'm very thankful for any help you can provide.
EDIT: Running Ubuntu 18.04.2. I can't recall what version I have on my install USB but it's slightly older. GRUB calls the two different versions I can boot to Ubuntu, with Linux 4.18.0-20-generic
and Ubuntu, with Linux 4.18.0-15-generic
as well as recovery options for both versions. Currently, only Ubuntu, with Linux 4.18.0-15-generic (recovery mode)
works.
