victor gasper:
1) Could you please post the missing information from a bad boot
following https://wiki.ubuntu.com/DebuggingKernelBoot ?
2) To clarify, when booting up and using GRUB to boot into an older
kernel, would this return to the previous behavior?
3) Regarding the suggested four kernel parameters, are you advising you
tested each one individually (not in combination) and it had no affect?
