Getting device/system info…

Flashrom is unable to read current firmware; cannot continue:

Steps to Reproduce

Expected Behavior

FW update script should complete correctly.

Works OK if I use a Linux Mint 22.3 live CD
Fails under Fedora 44 KDE Workstation full install

The answer is probably in the text below, but I’m pretty new to Linux and does not make sense to me yet. – Secure Boot state is DISABLED

Flashrom is unable to read current firmware; cannot continue:

then please email a report to [email protected] including a verbose (-V) log.
Thank you!

You may need to add ‘iomem=relaxed’ to your kernel parameters,
or trying running from a Live USB with a more permissive kernel (eg, Ubuntu 23.04+).

If you have UEFI SecureBoot enabled, you need to disable it to run
the script/update your firmware.

the script is telling you exactly what the issue is and how to resolve it. is that not clear?

as a new user, no, it is not clear to me.

as I said, I assumed the text was telling me the problem, but I don’t know what to do with the information to implement the fix, so I followed the last line…

add the kernel parameter ‘iomem=relaxed’ to your kernel boot params. fedora should have documentation on how to do that
