Getting Some error message on boot

[vsvinit0]

I am getting some errors on boot. Mostly I have fixed some of the errors by changing kernel parameters and changing some settings in bios. I tried to fix these remaining errors but I am not getting any proper solution. Is there any way to fix these errors or disable them.

To fix the dell_smbios error I have blacklisted this module in the blacklist.config file.

Did you try this kernel parameter yet: amdgpu.dc=0?

[vsvinit0]

Did you try this kernel parameter yet: amdgpu.dc=0?

No, I have not tried this parameter. By the way what this parameter does. Any details?

Kernel Parameters on my machine

It doesn't work. I added this kernel parameter and I am stuck on the boot screen with the error

But at least we got rid of the amdgpu errors.

Not sure, remove the amdgpu parameter again so you can boot, then check if there's a BIOS update first, and I'd also try the latest stable mainline kernel. For the latter, download all of these into an empty folder:
http://kernel.ubuntu.com/~kernel-ppa/ma ... 31_all.deb
http://kernel.ubuntu.com/~kernel-ppa/ma ... _amd64.deb
http://kernel.ubuntu.com/~kernel-ppa/ma ... _amd64.deb
http://kernel.ubuntu.com/~kernel-ppa/ma ... _amd64.deb

Now open a terminal window in that folder and run

Code: Select all

sudo dpkg -i *

Reboot and see if it helped.

Ok, I did what you suggested. But got two new errors

Was worth a try. You can go back to your original kernel via the GRUB menu (hold Shift after the BIOS screen to make it appear, you might have to press Esc in addition), select Advanced, then your previous kernel. Once you've booted back to your 4.15 kernel, remove the one I had you install:

Code: Select all

apt purge "linux-*4.19*"

Unfortunately that's all I had, there seem to be some incompatibility issues with your device. It's not uncommon with recent devices. You didn't say in your OP whether those errors actually cause issues, but unless they do it's probably not worth investing too much time into.

No these errors don't cause any issue or lag in my system. I just wanted to get rid of those errors. Actually a few days back I reinstalled this distro on my system as previously I was getting a lot of issues. This time I just tweak it to fix most of the errors. But still, I was not able to fix them completely. So I was seeking any help. Anyway thanks for the help gm10. I got to know a lot of new things and will experiment with your suggestions.

And one more thing I got timeshift installed on my machine can I use that to revert back the settings and configuration to the previous point.

[gm10]

Oh yes, sure, that's what Timeshift exists for.

And I'm sure your issues will eventually be resolved with a future BIOS/firmware/kernel/graphics driver update.
