This means that either the bisection is unreliable (it might be 100%
reproducible or you mixed up good/bad once), or that the arm-soc
branch was indeed good by itself but had a conflict with some other
change that torvalds merged earlier.
I would suggest to go back to the list I had extracted in my previous
email and revert all the commits that I identify there, on top of
linux-5.5-rc4. If some commit is not easily reverted, skip that one
at first.
Ideally this gets you a working kernel based on -rc4, and then
you can bisect that to find which revert fixed it.
