In particular, $ git bisect replay bisectlog Previous HEAD position was d54b1a9... perf script: Remove use of die/exit HEAD is now at a0d271c... Linux 3.6 Bisecting: 0 revisions left to test after this (roughly 0 steps) [d54b1a9e0eaca92cde678d19bd82b9594ed00450] perf script: Remove use of die/exit However, the patch that is problematic is the one before the one git bisect indicated. [commit 8d3eca20b9f31cf10088e283d704f6a71b9a4ee2]. I am running git 1.7.11.7.
