system booted. Seems it now set to auto for default.

Had a similar issue on a 20.04 install today after updating to 5.14.
Woke it up from suspend on 5.10.0-1057-oem. Rebooted once (some screen

manager, rebooted using the new 5.14.0-1024-oem kernel and it just hung.

Still the same with v5.16-rc8.

Is it a new or old system?
What's the last working kernel version for you?
Have you considered going back to the official kernel version for your

Another option you may have would be to try disabling that

1) Do an $ ls -lah /boot
2) look for config-5.15.6 file and nano into it. That's the
config for the kernel that Ubuntu used for building it.
3) ctrl+w and type or paste "CONFIG_UBSAN_TRAP" and hit enter. (paste
is ctrl+shift+v)
If it doesn't find it, then it is odd that it doesn't work for you

So as it stands, new 5.15.3 has no "CONFIG_UBSAN_TRAP" in config.
So for new kernels you can probably close this bug off as long as they
