I have a desktop that has problems with EFI booting from CD (e.g. for
Boot Repair). Is this likely to be the same issue as discussed here?
I have Gigabyte GA-Z97X-UD3H with F8 bios. sudo efibootmgr -v gives:
BootCurrent: 0001

Title:
corrupted BIOS due to Intel SPI bug in kernel
Status in Linux:
Unknown

Bug description:
An update to linux kernel on Ubuntu 17.10 that enabled the Intel SPI
drivers results in a serial flash that is read only in Intel Broadwell
and Haswell machines with serial flashes with SPI_NOR_HAS_LOCK set.
Symptoms:
* BIOS settings cannot be saved
* USB Boot impossible
* EFI entries read-only.
---
Fix: The issue was fixed in kernel version 4.13.0-21 by configuring
the kernel so it is not compiled with Intel SPI support. But previous
affected machines still suffered from a broken BIOS.
Repair: If you still can boot into Ubuntu, you can recover your BIOS
with the following steps:
1. Boot into Ubuntu
2. Download
http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+20170103+1_amd64.deb
3. Install the downloaded package:
$ sudo dpkg -i
linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+20170103+1_amd64.deb
4. Make sure the kernel is installed without any error. Once installed,
reboot.
5. At grub, choose the newly installed kernel. You can choose the "recovery"
mode.
6. Reboot and go to BIOS settings to confirm your BIOS has been recovered.
7. In case your BIOS is not recovered, reboot to the new kernel, then reboot
*once again* to the new kernel, do not enter BIOS settings before the reboot.
After the second reboot, check BIOS.
8. If your BIOS issue remains, download another kernel from
http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+clear+debug_amd64.deb,
and use dpkg to install it, then repeat steps 4 to 6.
After your BIOS is fixed, the kernel packages you just installed are
no longer needed, you can remove it by running 'sudo dpkg -r linux-
image-4.15.0-041500rc6-generic'.
The patch used to build the linux v4.15 kernel in step 8 can be found
at https://goo.gl/xUKJFR.

Test Case: Fix has been verified by our HWE team on affected hardware.
Regression Potential: Minimal, it's unlikely anyone is actually doing
anything which requires this driver.

Original Description:
Basically on Lenovo Y50-70 after installing Ubuntu 17.10, many users
reported a corrupted BIOS.
It's not possible to save new settings in BIOS anymore and after
rebooting, the system starts with the old settings.
Moreover (and most important) USB booting is not possible anymore
since USB is not recognized. It's very serious, since our machines do
not have a CDROM.
Lenovo forums at the moment are full of topics regading this issue.
Thank you!!
