escozzia,

Looks like it. You cannot rely on your toolchain to (re)build itself correctly as it seems to be broken.
Its worth booting into memtest to see what that says about your hardware.


Hmm I just did a memtest pass without any errors, so the hardware is probably okay.

I guess that means it's a toolchain rebuild for me - do you have any pointers on the best way to do that? Obviously just re-emerging everything won't work, but it seems as though just downloading binaries and replacing the installed ones would be a bit crazy

escozzia,

You need a setup as described in fix my Gentoo
Instead of using emerge to generate the required binaries, there is a script.

When you get the the part that reads
Code:
More Packages

emerge whatever you need. You don't need to do it all in one go. /home/rescue will stay around until you delete it and its only a chroot away. When you come back, don't forget the /usr/portage bind mount.
Do
Code:
/usr/portage/scripts/bootstrap.sh
That's actually stage1 of a stage1 install. It builds your toolchain. This script does not support resume.
You can probably install all the binaries you get, into your main system, with emerge -K too.

Hmm, I followed that guide, and then did

Code:

 emerge '=sys-kernel/gentoo-sources-4.1.15-rc1'
 


inside of the chrooted system, followed by

Code:

 emerge -K sys-apps/baselayout sys-apps/texinfo sys-devel/binutils sys-devel/gcc sys-devel/gettext sys-libs/glibc sys-libs/zlib virtual/libc sys-devel/bc
 source /etc/profile
 env-update
 


Inside the parent system, then rebuilt 4.1.12. However, it still doesn't boot.

I did try building the emerged 4.1.15 from inside of the chrooted system, and that one does boot, so it's looking likely that I just didn't emerge the package that's at fault.

I'll just try to

Code:

emerge -e world


from the child and then install every single binary package into the parent, which might take a while.

escozzia,

Your parent world file will be polluted with @system packages.

That
Code:
emerge -K sys-apps/baselayout sys-apps/texinfo sys-devel/binutils sys-devel/gcc sys-devel/gettext sys-libs/glibc sys-libs/zlib virtual/libc sys-devel/bc

should have been -K1 or -K --oneshot.

There is an emerge option to remove entries from the world file without uninstalling the package.

Hurmm still no good. I did the

Code:

emerge -e world


in the child, followed by a

Code:

quickpgk '*/*'


just to make sure I got everything, then went back to the parent and did

Code:

emerge -K1 $(find /usr/portage/packages/ -type f -name '*.tbz2' | egrep -v 'udev|sandbox' | sed -e 's/.*packages\/\(.*\)-[0-9]\+.*.tbz2/\1/g' | xargs)


I rebooted, rebuilt the kernel and still no good. The child kernel still works okay though. I'm stumped - that command reinstalled just about everything I can imagine could be the source (except for udev and sandbox - could it be those? udev was bizarrely giving me a conflict, and reinstalling sandbox caused every build to fail)
