Re: Very serious kernel+Intel SPI driver bug...
Did I understood correctly that whole Lenovo was unable to make some little fix for their firmware? And whole ubuntu kernel required to remove BIOS chip write protection?
Windows assumes I'm stupid but Linux demands proof of it

This isn't Lenovo's fault, Lenovo bought this firmware from Insyde, it's Insyde that must be held responsible for the fix. The fact this is a third party hardware is why we are now seeing reports from Dell, Toshiba, Acer, and Mediacom users, I'll be surprised if there's not more.

Yes. But not only firmware non Lenovo's. Also a CPU from Intel, HDD probably from Seagate Technology, etc. Just curious, what Lenovo doing else and responsible for what? May be they only glues their label on the case. If so, then no other questions.

That's more or less what Lenovo now does. When what is now called Lenovo was owned by IBM they could manufacturer an entire computer using they own components.
When Intel screwed up the floating point in the first pentium, Intel had pay for the recall. When Sony batteries went bad Sony had pay for the recall. In these examples the recall is paid for by Intel and Sony and Lenovo would do the customer contact.

I think there is a lot more to this than what we are being told. On the Lenovo forums, the person that started the thread from back in March says they have a problem saving UEFI settings and never mentions Linux at all. https://forums.lenovo.com/t5/forums/v3_ ... -id/154203
There is even a link on the Ubuntu bug report to a kernel.org bug that had been fixed. One person on the Mint IRC said his Lenovo was bricked in March and that was before 17.10 and I don't know if they had the problem 4.11 rc1 kernel. Some people including the one on IRC claimed this bricked their computer which might mean the UEFI register had limited writes because others claim they were able to switch to a different kernel and have no more issues, including one from a friend of mine on Ubuntu Forums https://ubuntuforums.org/showthread.php ... st13724690

Re: Very serious kernel+Intel SPI driver bug...
I was able to fix my BIOS write protection issue with the following steps (if anyone has the same issue for some reason):
- 1. Install Ukuu
2. Select the kernel 4.14.9 and select Install. wait for the installation to be completed and then restart the PC.
Code: Select all
sudo apt-add-repository -y ppa:teejee2008/ppa sudo apt-get update sudo apt-get install ukuu
3. Restart the system with the latest kernel
4. From GRUB select the option which starts with "Advanced options".
5. Select Linux 4.14.9-generic. wait for the system to load completely.
6. Restart again and go into the BIOS
- 1. Remove the kernel using UKUU
2. remove UKUU:3. install ppa-purge:Code: Select all
sudo apt purge ukuu
4. Remove the PPA, downgrading gracefully packages it provided to packages provided by official repositories:Code: Select all
sudo apt-get install ppa-purge
Code: Select all
sudo ppa-purge ppa:teejee2008/ppa
