OK, I captured the output. No diffs, as of course reverting things means one kernel was called 3.15-rc1 and one 3.15-rc1+ which meant more or less every line changed. It seems that on stock 3.15-rc1 (which fails to build) after running depmod it kicks into restore_upstream_debianization which goes down a path which causes the file permission failures Wheras 3.15-rc1 with the problem commit reverted this doesn't happen. This is a really weird bug, I've tried reverting individual hunks of the problem commit manually and it is not clear at all to me what is triggering this.
