The .meta/cfg/kernel-cache directory does exist in the build directory after the failure.

Chat from Bruce on IM:

"""
yah. but it is so very weird, it has to be the move to work-shared (part of the kernel_checkout) and the configuration/meta-data phase.
I'll check the ordering between those tasks.
both just say: before do_patch
so I bet they race.

Comment 1 Bruce Ashfield 2015-05-07 18:32:24 UTC

this should be the fix:

Comment 2 Ross Burton 2015-05-07 19:12:59 UTC

Yeah that looks like a good candidate!
