What's the last working kernel version for you?
Have you considered going back to the official kernel version for your
Ubuntu (if it works?)?
Another option you may have would be to try disabling that
"...SANITZE_ALL" config and rebuild the kernel from kernel.org using
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
Does it have "CONFIG_UBSAN_TRAP" set in the config?

Kernel works ok.
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
don't reintroduce it.

Looks like they may have removed "CONFIG_UBSAN_TRAP" from the kernel
config of 5.15.3!
Only this is in the config...
```
# CONFIG_UBSAN is not set
```
I'm building it now to see if it is ok and works.

Fails for me too 5.15.1 on Penryn, Ivybridge, Haswell and guest VMs on

I had to rebuild the kernel from kernel.org using the config from Ubuntu

After that it worked on all the above architectures.

Point 1) above WORKS on zen3, haswell, and ivybridge.
That means disabled 'CONFIG_UBSAN_TRAP' in the kernel config prior to building.

I wrote down some high-level steps in #32.

You guys mocking around trying to hack headers and wotnot, just build
the bloody kernel and you'll have a full kernel without wondering if you
broke something by hacking stuff! You could have built the kernel a
100x by now!

2) build libbpf from hirsute

Need this fixed as we're jumping through hoops to get newer kernels into

I've been building dwarves and libbpf using the c library from 20.04. I
believe you are too Tuxinvader.
But yes, there are extra hoops to jump over having to do those! If they
get it in then that would be a couple less things to boilerplate.
Would be good if they fixed DKMS as well
If you want to stay with Ubuntu 20.04 LTS with latest stable mainline, you'll
need to build it.
Otherwise, try openSuse-Tumbleweed or Fedora.
I'm sticking with ubuntu so just building my own kernels. Runs faster
now as well since it is optimised for my rig specifically now.

Thanks to this "bug", yes it IS a"bug"; thousands of ubuntu users have

I never had to compile a linux kernel until this happened to 5.11.17+!

The silver lining here is that my ivy-bridge
What a joke! So how is the community going to contribute, help, and
support the mainline kernels for "debug purposes" now?
Everyone on LTS that wants mainline will now be forced to compile their
own kernels or arbitrarily trust PPAs of unofficial 3rd parties if
choosing to stay with Ubuntu.
@eitch
Try Dougss steps without the aggressive optimisations first so you get
the hang of it. Make sure it works and your hardware all works.
My steps are a little different to Doug's and perhaps a little more
complicated. But once you get the hang of it, it is repeatable and can be
PPAs are a mechanism for "moving around raw debs"... ;-)
But you have a point, however if all systems are in the same network, it
is far much more easier to copy all debs to all servers and sudo dpkg

How do we remove the source?

Mate, go ahead and close it. I haven't exerienced it since. it's been a
while but I believe package dependencies caused the issue.
If it happens again, I'll put more effort into the debug message.
