This happens when updating initramfs under 3.18.0-rc3 and -rc4. Can't remember rc1 and rc2 in detail.
Specifically 4 warning messages causes initrd to not be created (and then you can't boot) when verbose is turned off: [code] W: Possible missing firmware /lib/firmware/rtl_nic/rtl8107e-2.fw for module r8169 W: Possible missing firmware /lib/firmware/rtl_nic/rtl8107e-1.fw for module r8169 W: Possible missing firmware /lib/firmware/rtl_nic/rtl8168h-2.fw for module r8169 W: Possible missing firmware /lib/firmware/rtl_nic/rtl8168h-1.fw for module r8169 [/ccode] appending the -v or -vv parameter to update-initramfs command line allows the initrd.img to be created. Testing it is another issue of course. Changes from plain-vanilla include use of dkms for EnhanceIO modules (used for HDD caching to 32gb mSATA SSD) which are coded into /usr/share /initramfs-tools/scripts/local-top in a script file. update-initramfs runs normally under 3.17.1 and 3.16.6 kernels without the "-v" parameter.
