Re: Unable to shut down or suspend

With CONFIG_MODVERSIONS=N a3db3d3a52f0f159e0aa996792987acd8c14d2ad boots successfully on a system for me.
Sorry question was badly phrased I meant would you change it in the context of just for this git bisection.
edit:
change CONFIG_MODVERSION to CONFIG_MODVERSIONS

Re: Unable to shut down or suspend

I'd rather first skip out of this breakage and see wheter you end up in a usable bisect range (ie. are still good on the actual error) because
a) compile time
b) remote but still possible relation of this particular setting with the error - iff the bug was introduced in a CONFIG_MODVERSIONS branch, you can test yourself to death until you figure that you'll never run bad again ;-)
(So at least you'll have to test the known bad revision before anything else)

Re: Unable to shut down or suspend

I wonder what percentage of the remaining search space is bootable with CONFIG_MODVERSIONS=Y
Edit:
Second skip in triggers a Restart config... and hence a full rebuild ( would say that negates the compile time argument )
Edit2:
80439a1704e811697ee01fd09dd95dd10790bc93 does not have the CONFIG_MODVERSIONS issue but does not boot on system here either.
Edit3:
1e88ab6fbbaacbd79dd14ab9ceec7a595611248d does not have the CONFIG_MODVERSIONS issue and does boot I suspect the previous one I said did not boot was bootable after all.

Again thanks to seth and loqs for their kind help.

I could boot 1e88ab6fbbaacbd79dd14ab9ceec7a595611248d and it's a bad one.
But I could not boot e17705c43b4273d2587297d5f8168ee432d9c94a, I then skipped three times and could not boot the resulting commit either (e9117e5099ea29592c2a6180f368951948837a8b).

Side question : is it normal that uname always returns the version of the very first commit (4.9.0-rc5-g69973b830859). Looks to me that this value is in linux.install.pkg and it is not updated each step of the bisect. I don't think it's a big deal if you know what you're doing but that was confusing for me at first.

Re: Unable to shut down or suspend

I think it is this from the PKGBUILD's prepare function which is not used every build because makepkg is using the existing srcdir for the bisect.

  sed -i "s|CONFIG_LOCALVERSION=.*|CONFIG_LOCALVERSION=\"-${pkgver##*.}\"|g" ./.config

The rest of the uname should be changing if my understanding is correct.
