I may be useful to add "debug ignore_loglevel" to the kernel boot
command line to get more debugging information during boot to see which
module is tripping this issue.
edit the /etc/default/grub (as the root user) and add the debug and
ignore_loglevel keywords to the GRUB_CMDLINE_LINUX_DEFAULT
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash debug ignore_loglevel"
then run:
sudo update-grub
and reboot. Can you then attach the full kernel log.
Thanks.
