Description Dennis Schridde 2012-12-18 18:35:58 UTC 
I tried to build versions 2.6.32-r116, 3.2.34-r2, 3.2.35, 3.7.0 of sys-kernel/hardened-sources using sys-devel/gcc-4.6.3 and while the build succeeded, the resulting kernel images did not boot. (After elilo loaded the image, nothing happened, and the system rebooted after a while.)

A kernel compiled with the same config using gcc-4.5.4 boots.
# make clean
# make CC=gcc-4.5.4

This on a HP rx2600 ia64 machine. Kernel config for 3.7.0: attachment #332620 [details] - I can provide the others upon request.

Reproducible: Always

Can you get the stuff that listed in the Kernel Crashes/Hangs in

  http://en.wikibooks.org/wiki/Grsecurity/Reporting_Bugs

and pass them along upstream.  I can't really do much with ia64.

does vanilla built with the same gcc fail as well?

sys-kernel/vanilla-sources-3.7.9, compiled with sys-devel/gcc-4.7.2, linked with sys-devel/binutils-2.22-r1, fails to boot. Config attached.

config, System.map, vmlinuz all available at: http://kynes.de/~dschridde/vanilla-3.7.9.tar.xz

i guess this is then something you'll have to work out on lkml and the kernel bugzilla (https://bugzilla.kernel.org/).
Comment 7 Dennis Schridde 2013-02-22 20:34:22 UTC 
I created a bugreport upstream: https://bugzilla.kernel.org/show_bug.cgi?id=54251
