Arch Linux

Description:
Since I've changed my PC sometimes mkinitcpio gives an error during the autodetection of the modules, but it goes on and produces a broken initramfs (it misses at least some modules) leaving the system in an unbootable state. It doesn't happen all the times, but in the logs I can count 7 occurrences in about 60 runs in the last 4 months during system upgrades.

Additional info:
* mkinitcpio 36-1

Here is the log of a failed run:

Notice the lines about sort and modprobe and the fact that the log ends with "Image generation successful". Throwing an error would at least allow me to notice the issue and relaunch the script manually (I do this when I notice it).

Steps to reproduce:

Honestly I don't know, it happens randomly. Let me know if you need further info.
