The only lines that have multiple entries are two interrupts with ohci_hdc and snd_hda_intel, that should be no problem. The two ahci entries have their own interrupts. I did not yet find the time to remove the plasmoids (all is fine in other window managers, or for another user with a plain unconfigured KDE desktop), today I dealt with a horrible and weird qt upgrade experience on another PC. Finally I was able to downgrade to 4.7, and at least stuff is working again there. Wonko
