Comment 1 Bruce Ashfield 2013-03-03 04:47:25 UTC

Mark: I haven't changed anything in the kernel itself, is this due to the
kernel-module packaging changes ? Are there missing INC_PRs somewhere ?

Comment 2 Richard Purdie 2013-03-03 10:42:44 UTC

The issue here is that we swiched to the PR server model to maintain incremental revisions but the autobuilder doesn't use the PR server.

Our options are to:

a) Disable this particular check in build history on the autobuilder
b) Setup PR server on the autobuilder

Comment 3 Richard Purdie 2013-03-03 13:08:14 UTC

I've sent out a patch which implements a), the only change needed would then be adding:

BUILDHISTORY_CHECKVERBACKWARDS = "0"

to the autobuilder configuration.

Comment 4 Beth Flanagan 2013-03-05 01:29:53 UTC

I have this disabled on the production ab and the new ab codebase.
