Hello,

When I try to cherry-pick the tip of a review.coreboot.org patchset it works.

When I try to cherry-pick previous patchsets it fails.

Why is that. Details below.

I need to cherry-pick previous patchsets as it is part of a script that tries to reproduce a previous snapshot to my local machine.

bash$ git remote -v

cros https://chromium.googlesource.com/chromiumos/third_party/coreboot (fetch)

cros https://chromium.googlesource.com/chromiumos/third_party/coreboot (push)

bash$

bash$ git log --oneline -n5

bash$

bash$ git fetch https://review.coreboot.org/coreboot refs/changes/34/73534/2 && git cherry-pick FETCH_HEAD

I found related topics and workarounds here but I think the issue has to do with how gerrit works internally.

Please explain why it fails to cherry-pick previous patchsets.
