Would it be OK for you to rebase your for-next branch on v5.2-rc2 or cherry-pick the revert to avoid recurring bisections? Ideally this should have been fixed or reverted in mainline before v5.2-rc1 was released, or even earlier when this was first found in -next on 13th May. Unfortunately it was overlooked and then spread to other branches like yours. Thanks, Guillaume

I'm afraid it's gonna spread to even more for-next branches, as most subsystem maintainers base their for-next branch on the previous rc1 release. Typically maintainers do not rebase their for-next branches, and do not cherry-pick fixes, unless they are critical for their subsystem. So you can expect this to show up in e.g. the m68k for-next branch soon... Can't you mark this as a known issue, to prevent spending cycles on the same bisection, and sending out more bisection reports for the same issue? Thanks! Gr{oetje,eeting}s, Geert

Usually what we would want for development trees is to ignore any errors coming from a commit on a release candidate branch, like -rcN, as it is not directly under our control. Yours, Linus Walleij

Not really, so I've disabled bisections in the linux-gpio tree and a few other maintainers' trees for now. I'll see if we can come up with a more systematic way of suppressing bisections in similar cases (i.e. the issue has been fixed in mainline later than the base commit for the branch being tested). Thanks, Guillaume

Having a systematic way would be good, else you will have to disable most other maintainers' trees soon, severely limiting test coverage, or fall back to linux-next testing only, as linux-next will always include\ latest mainline.

I think this is what the zeroday autobuilder does because they never seem to show this problem. Thanks for looking into it! Yours, Linus Walleij

Thanks for looking > into it! I've got a feeling they do this by deduping after doing the bisection; they also used to have a system where they'd merge a bunch of trees together and do the bisect on that to save repeating bisects.

And it requires setting the tshut polarity before select pinctrl. When the temperature sensor mode is set to 0, it will automatically reset the board via the Clock-Reset-Unit (CRU) if the over temperature threshold is reached. However, when the pinctrl initializes, it does a transition to "otp_out" which may lead the SoC restart all the time. "otp_out" IO may be connected to the RESET circuit on the hardware. If the IO is in the wrong state, it will trigger RESET. (similar to the effect of pressing the RESET button) which will cause the soc to restart all the time.
