X86/cpu: SGX disable by BIOS And ACPI BIOS error (bug): Could not resolve symbol

[jony]

Zorin was install in my laptop
before installing

TPM and Secure boot was disabled.

After installed I trun on both TPM and Secure boot. Everything work fine.

For some region I wanted a clean install of zorin os that why I try to reinstall the zorin os again.

with
TPM in is enabled
Secure boot enabled

This time it showing me this message in the first picture??

I can use the OS but the message showing eveytime I on the laptop

when fist time its install with TPM and Secure boot was enabled. it show perform mok management (2nd picture).

options shows

continue boot
enroll Mok
enroll key form disk
enroll hash form disk

I saw a video that use 2nd option to boot. I use the first option. did i do any mistake. is that why I saw this massage.

Can I fix those thing?? Or it will fix automatically with next version of zorin os.
Should I avoid it???? Does it do any harm like security issue and slow the os or laptop?????

or I should reinstall the Zorin os and in perform Mok management use the 2nd option. can it be fix by doing this need help what should I do???

Hitting continue boot should boot into the OS normally.

It show for first time. It never showed again. is this going to create any problem in future??

I see that issue appear on my laptop every time I start it up. It doesn't do much to my laptop (everything is fine), so it's enough to be ignored.

if I ignored it is this going to create any problem in future?? Because I will not reinstall the zorin os again and again. I want to use it as normal desktop computer.

is there any ways to fix this issue???

I think that if i disable the secure boot and install the zorin os and and enable it the should fix but is it a right way?? Means the secure boot functionality will work or as I off the secure boot and install the os and then on the secure boot does that's make any sense???

I found out a another post that said to use the old kernal to solved the issue. using a old kernal is it good or it's cause any security issue??

[HOW TO] set an older kernel to default boot

You may need to use an earlier kernel than the current kernel used by Zorin. This method allows you to set the kernel that you will boot into by default. To set the new kernel to default: Boot into the kernel you wish to be Saved. Open terminal and run: sudo nano /etc/default/grub Change GRUB_DEFAULT=0 to GRUB_DEFAULT=saved Hit enter to drop down a line. Add GRUB_SAVEDEFAULT=true ctrl+x to exit, then the y key to say yes to save, then the enter key to save as current configuration. Ru…

I also found out another solution that In bios there can a be SGX enable and disable option. I saw in my bios I don't have that option.

This message annoying I think zorin must do something to stop it those laptop doesnot have the SGX option.

Errors between start and logscreen

its a kernel bug, if your system is booting its not causing an issue If they annoy you enough to get rid of, you can silence them by 2 +100 You can get rid of those ACPI Error messages by Open /etc/default/grub in an editor with root access. In your case I believe Ubuntu uses gedit as it's text editor: sudo gedit /etc/default/grub The line with GRUB_CMDLINE_LINUX_DEFAULT, add the loglevel=3 part. The original looks like GRUB_CMDLINE_LINUX_DEFAULT='quiet splash' Change it to this: G…

maybe that same solution might help you get rid of (at least) the error messages

is there any ways to fix this issue permanently???

You don't need secure boot to use Linux, if you want to you can (I do on my laptop) you would select enroll MOK and use the password for secure you supplied in setup. My works vpn checks for it even on Linux which is why I have it.

For the cpc messages that seems to be a kernel bug in 5x that doesn't cause any issues an older acpi kernel module is called but is now missing (depreciated) as far as I can tell. Acpi handles power and auto configuration of devices, if you are having hardware issue those messages can help, but if they due to a bug you can use the above link to ignore them on boot.

@seanhinkley

you would select enroll MOK and use the password for secure you supplied in setup

But it's show only first time when I setup the OS. The bios never ask it again. If I want to do it I need to setup the OS again. Should I do that or stay like this.

Just leave as is, it's not needed for Linux usually.

Microsoft uses it as part of the activation and digital key system and some corporate software and tracking software use it.

@seanhinkley

if you are having hardware issue those messages can help, but if they due to a bug you can use the above link to ignore them on boot.

so this kernal bug thing stay forever or it will fix by zorin in some version. if it fix by an update I don't mind if the message show or not but there should be a fix. it cannot stay forever????

[seanhinkley]

This is from the Linux kernel and affects most Linux distro not just Zorin,it might be fixed in kernel 6 which Zorin may upgrade to (might be in v17) but I'm not 100% sure what that release roadmap looks like.

If you're okay with the messages then you can just leave them. They are just informational

The first one is just letting you know SGX is not enabled
And the other ones are just letting you know that an ACPI module could not be loaded to detect because the module is missing from the kernel.
