Rebuilding from that point on will make the warning go away. I'm believe the patch is still being applied even when the warning appears (though I am not certain), but the message might lead you to believe otherwise. This warning should probably not appear if the patch is found in a second location. 33536 1 bluelightning 2013-06-04 09:02:49 +0000 Patch sent to the bitbake-devel mailing list to fix this. FYI, you can work around this problem by running "touch" on the recipe file - no need to delete the cache. You are correct in that the patch file is being applied even when the warning is shown; all that breaks is the calculation of the checksum which we use to trigger a re-run of do_fetch and all tasks that depend upon it when one of the local files referred to in SRC_URI changes. 33794 2 bluelightning 2013-06-12 09:34:18 +0000 Patch merged to master: http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=be78283e6cd7bea2eb1a5c5b797f1a6315468da5
