[17:54] <roddy> Is there a problem with dell motherboards and kernel 6.6? I have noble installed and crashed half a dozen times using kernel 6.6. Only kernel 6.5 works.
[17:56] <roddy> Anyone?
[17:56] <lotuspsychje> roddy: kernel 6.6 just came out recently on noble
[17:56] <lotuspsychje> roddy: do you have a bug ID on your issue yet?
[17:56] <roddy> Yes, unable to use it.
[17:57] <arraybolt3> also *what* Dell machine are you using? A Dell Alienware failure is probably going to be very different than a Dell Optiplex failure.
[17:57] <roddy> No bug issue filed.
[17:57] <lotuspsychje> can you elaborate at wich point exactly things go wrong roddy 
[17:58] <roddy> It starts up then freezes halfway running kernel 6.6. Have to revert to 6.5. I think the issue is Intel TPP.
[17:59] <roddy> I'm using XPS 8940.
[18:00] <roddy> I also have problems booting the Optiplex 7070 with 6.6 kernel. 
[18:01] <arraybolt3> I have an Optiplex 9020 here, I can give it a whirl.
[18:01] <arraybolt3> might be too old though
[18:02] <roddy> Where do you go to file bug reports about noble and kernel 6.6?
[18:02] <arraybolt3> run `ubuntu-bug linux` in a terminal and follow the prompts
[18:03] <lotuspsychje> package linux might not work anymore currently due that apport bug the devs are working on
[18:03] <lotuspsychje> bug #2018128

[18:03] <arraybolt3> oh fun
[18:03] <roddy> 9020 is way too old I had a couple. 
[18:03] <arraybolt3> though the kernel in Noble isn't HWE I don't think.
[18:04] <lotuspsychje> arraybolt3: i know, but due the devs are working on it, seems to be not working on package linux currently
[18:04] <arraybolt3> bleh
[18:04] <lotuspsychje> try it, see if you can reproduce
[18:05] <lotuspsychje> i also filed that cloud init warning
[18:05] <lotuspsychje> bug #2044159

[18:06] <roddy> Ubuntu isn't the only one having problems with 6.6. Archlinux flavors also have issues. Why release a kernel that's full of bugs?
[18:06] <lotuspsychje> roddy: ubuntu 24.04 is in devel branch currently, bugs 'can' occur in this stage
[18:06] <arraybolt3> and not everyone tests on exactly your hardware
[18:07] <lotuspsychje> and kernel versions can also influence things on specific hardware indeed
[18:07] <arraybolt3> regressions are treated seriously in the Linux project and should be treated seriously by Ubuntu, but it's impossible to catch every single thing
[18:07] <arraybolt3> which is why the kernel version doesn't change very frequently once an Ubuntu release is released
[18:08] <roddy> I suspect the worst issue has to do with TPM2 and PTT and other brand's Security settings.
[18:09] <lotuspsychje> roddy: also, some brands can benefit OEM kernel versions, maybe thats an idea for your case
[18:10] <lotuspsychje> roddy: a good starting point would also be collecting your errors/logs/dmesg on booting kernel 6.6 and share with the volunteers here
[18:12] <roddy> I cannot successfully boot kernel 6.6. It freezes/crashes midway through the run.
[18:14] <roddy> I tried ubuntu-bug linux-image and it cannot find cloud-specific data ... hmmmm...
[18:15] <lotuspsychje> roddy: you can try to catch journal logs from a previous boot
[18:16] <lotuspsychje> journalctl -b -1
[18:18] <lotuspsychje> or journalctl --list-boots , to find your 6.6 boot
[18:18] <roddy> I have been using ubuntu since it was formed first. Been using development versions until this version with kernel 6.6 is crazy.
[18:19] <roddy> Yeah I have reinstalled ubuntu at least half a dozen times fighting kernel 6.6...
[18:21] <roddy> Warty Warthog 4.10 was the initial ubuntu version. Ubuntu user 12 years running now.
[19:06] <johnjohn101> hi arraybolt3
[19:06] <arraybolt3> johnjohn101: heya! long time no see :)
[19:19] <johnjohn101> we'll talk soon
[19:58] <ChmEarl> grep UBSAN /boot/config-6.6*   <-- still turned on in 6.6?
[19:58] <ChmEarl> I rebuilt the 6.5 kernel with UBSAN off
