Hello,
first time I’m trying OpenMandriva.
I’d actually want to check out how is the OOTB support for my Dell XPS 9640 with Linux 6.10 and Plasma 6.
On boot, after selecting the live option, the process stops with a fatal error message regarding
Spectre V2: WARNING: Unprivileged eBPF is enabled with eIBRS on, data leaks possible via Spectre v2 BHB attacks!
and giving option to Ctrl+D to continue.
Anything obvious I am missing?
TIA.
Regards.
is just a warning (like others that we don’t notice), in coincidence with the system that stops, so not related.
Did you verified the downloaded file checksums?
Alternatively you can try the full featured ISO and see if anything will change
ROME plasma6 x86_64
Also cannot be excluded some hw (incompatible or not seen (?)) issue.

@ilgrosso welcome.
Welcome to OpenMandriva and our forum. This forum is for users of OpenMandriva Linux operating systems.
OpenMandriva Forums are primarily users helping other users.
You are welcome to talk to our developers at OpenMandriva Chat.
Users with a problem need to read How to get better results when posting about problems before reporting any issue or problem. The article is not too long and Do Read.
When a new user has an issue please look in the documentation for OMLx. OpenMandriva wiki, Forum Resources guide and the “Search” function of the forum.
If you don’t find what you are looking for, try an Internet search. One can find out a lot from documentation or forum posts at other Linux distros. If user finds something written for another distro but you have some doubt ask at OpenMandriva Chat.
For serious technical issues and package/feature requests please file a bug report here.
Note: We are a small group. All the contributors and developers here are unpaid volunteers.
You can make OpenMandriva grow and improve by getting involved
Any help with testing would be appreciated whether one is technically proficient or a very non-technical user. The more people and more hardware we can get involved the better we can make OMLx releases and packaging. We do a lot of testing in VM’s as well. Developers tend to use Qemu, most user level testers use VirtualBox.
I am not 100% sure about what I am about to write. But based on what I know about OMLx:
That does not say fatal error. The Spectre V2 warning is a warning and probably not related to the boot process stopping. You would probably get a faster answer by asking OM developers at OpenMandriva Chat. I am not a developer, user level knowledge is me, but I will check in to this.
Edit: Regarding not booting on that hw we would need more information than you have provided to diagnose.
@ilgrosso also you could try when you get to that point in the boot process press Ctrl>D and at the prompt type either startplasma-x11 or startx and report what happens or what error you might see. Not booting would usually be something in hardware that is incompatible with graphics high on the list of suspects. Edit: The other thing we would like to see is all the ouput of the boot process which is not so easy for some users. As I recall you would press Ctrl>D and at the prompt type:
dmesg > dmesg.txt
journalctl > journalctl.txt
Copy those files to a flash drive and then post them here. With those files we then have something developers can work on. Edit: And if there is a problem we do want to fix it or at least try.

Booted ROME P6-X11 iso (build id 3243) and I do not see that Spectre warning. What I see here is:
$ dmesg | grep Spectre
[Tue Jul 23 18:32:29 2024] Spectre V1 : Mitigation: usercopy/swapgs barriers and __user pointer sanitization
[Tue Jul 23 18:32:29 2024] Spectre V2 : Mitigation: Retpolines

[Tue Jul 23 18:32:29 2024] Spectre V2 : Update user space SMT mitigation: STIBP always-on
and:
$ journalctl -q | grep Spectre
so journal shows nothing at all regarding Spectre. The only possibilities as to why @ilgrosso is seeing that warning do not make sense. Something in slim iso? I doubt that, I would think this is strictly a kernel function. Something in the Dell XPS 9640 hw? I doubt that also. I now need to seek professional help on this issue.
I still am inclined to believe the Spectre warning and the not booting are separate issues. But I could be wrong.
I made a big problem solving mistake here. I did not begin at the beginning. In a not booting iso situation the first steps are:
We ususlly recommend to do the download again. Check checksums then copy the .iso again with a recommended application like OM Image Writer.
Sorry for so much posting and wordiness but I am trying to do multiple things at once and well…
7 posts were split to a new topic: Why some OMLx systems need mitigations=off?
Thank you very much for your hints.
By looking at dmesg output I did notice some disk access errors; burning the downloaded ISO again was enough to fix.
Now the system boots up correctly but unfortunately the screen is cluttered by multiple horizontal colored lines.
It seems a monitor - rather than graphics device - issue, since the external HDMI monitor works fine.
I’ve got the same behavior with Linux 6.10 and other distros, so this is really not an OpenMandriva problem, which I need to fix anyway.
FYI it seems that adding
i915.enable_psr=0
is fixing the issue.
That happened to me as well, but only in live mode -installed system boots perfectly- and just for a brief time, if I remember correctly at plymouth screen.
I split some posts out of this for Why some OMLx systems need mitigations=off?. I hope I did an adequate job of this.
