[linux-yocto] [yocto] [PATCH 0/1] [linux-yocto-3.0] boot-live.cfg: enable BLK_DEV_INITRD in kernel

Wed Sep 19 14:55:12 PDT 2012

FYI: I've been using linux-yocto 3.2.  After doing a git pull recently,
I found both my own BSP and crownbay-noemgd to be miss configured, both
for linux-yocto and for xorg.conf, like it couldn't find the
configuration files.  I think the root problem with files not being
found may be a little larger than just the linux-yocto-3.0 bake file.
It was a lot of commits grabbed all at once, and I haven't had time to
isolate which commit changed the behavior.  Restoring a backup of the
files from before the pull restored the prior configuration behavior.
