Intel – Fix for Atom MMC/GPT warning..

I had been getting a warning on boot with recent kernels on my Intel Atom-based UP system, and found a workaround..    The error flagged is – apparently – harmless, and is due to systemd not being able to recognise some mmc disk partitions at that stage of the boot process..

[ 5.124250] systemd-gpt-auto-generator[416]: Failed to dissect: Input/output error
......

More background details here:   https://github.com/systemd/systemd/issues/5806 – and thanks to kwizart for the suggested fix/workaround..

The workaround is to add systemd.gpt_auto=0 to the kernel command line, and I can confirm that this removes the warning with Kernel 4.13.2 (Fedora 27)
