Hi Christophe,

Thanks for your answer but I think I don't know how it works with the cherry-pick.

$ git bisect start

As you suspect the problem to be specific to powerpc, I can do

git bisect start -- arch/powerpc

quoted

$ git bisect good 68a32ba14177d4a21c4a9a941cf1d7aea86d436f
$ git bisect bad c70a4be130de333ea079c59da41cc959712bb01c

You said that powerpc-5.13-1 is bad so you can narrow the search I think:

git bisect bad powerpc-5.13-1
git bisect good 887f3ceb51cd3~

I tried it but without any success.

git bisect bad powerpc-5.13-1

Output:
fatal: Needed a single revision
Bad rev input: powerpc-5.13-1

I don't understand, on my side it works. Maybe a difference between your version of git and mine.

In that case, just use the SHA corresponding to the merge:

git bisect bad c70a4be130de333ea079c59da41cc959712bb01c
