Mkinitcpio "ERROR: file not found..."

view story

https://bbs.archlinux.org – I imagine the answer to this problem is SOMEWHERE but I can't find the solution. I ran sudo pacman -Syu and got this error message with mkinitcpio: ERROR: file not found: '/usr/lib/modprobe.d/usb-load-ehci-first.conf'I saw this bug but my config file is cut off before the mentioned "line 36," so it doesn't help me. I suspect it has something to do with the filesystem because not too long ago I had to create a symlink at /etc/mtab because the system wasn't reading the mount points. I also noticed if I try to upgrade filesystem I get this error: filesystem: /et (HowTos)
