[SOLVED] [mkinitcpio] initramfs "build error" messages since v.18-1

Question

Hi everybody,
Since the update from mkinitcpio 17-1 to 18-1 I get those build error messages while running mkinitcpio:
# mkinitcpio -p linux

However I can still boot and everything seems mostly fine. I haven't changed anything to my /etc/mkinitcpio.conf, here are the only customized parts:
MODULES="i915 dm_snapshot"
HOOKS="base udev autodetect modconf block keymap encrypt lvm2 filesystems keyboard fsck
I'm using an encrypted root (ext4 over LVM over LUKS) and boot partition is contained in an (unencrypted) LVM logical volume. I also specify a few i915 module options in an /etc/modprobe.d/modprobe.conf file as per the Intel Graphics wiki page:
# Intel graphics driver power-saving option :
options i915 i915_enable_rc6=7 i915_enable_fbc=1 lvds_downclock=1
Never had any such warnings before, but now it appears each and every time I update or reinstall my kernel (the default one). I went through Mkinitcpio wiki page, tried putting question marks after the listed modules and rebuilding but it didn't change anything... Any ideas?
Btw, I don't use any specific compression option and had the regular lzo name change during the same full system upgrade that updated mkinitcpio and linux.
Thanks

Answer 1

Yes indeed, removing /etc/modprobe.d/modprobe.conf~ hidden backup file solved the warning issue. Strange but thanks ukhippo, I hadn't thought about checking other subforums!
