I tried multiple, also 1.6, same issues remain.

Some issues:

My private bitbake collection has customized copies of upstream .bb.
Although my private bitbake collection has a higher priority, I
noticed bitbake "randomly" selecting either the upstream or local
collection for packages which have multiple providers left.

In one case (ixp4xx-kernel) if I run "bitbake ixp4xx-kernel -c patch",
then "bitbake ixp4xx-kernel" it selects my private .bb for the first
bitbake, and then selects the upstream .bb for the second bitbake
build.

One machine notes about multiple providers for kernel-image-, whereas
the other does not.

They run the exact same copies of the upstream sources, local
collection and the  bitbake tool.
