Subject: Kernel compiled with 4.7.1-8 fails to boot

Date: Wed, 12 Sep 2012 22:13:02 +0200

Package: gcc-4.7
Version: 4.7.1-8
Severity: normal


I cannot boot 3.6-rc5 (and some later) kernels. It blocks the kernel at very beginning (uncompress?)

dpkg -i *_4.7.1-7_* on /var/cache/apt/archives/ solved my problems.

Reproducible (but not very debuggable).

 - does this mean, that earlier kernels built with -8 work ok?

 - architecture, optimization flags?
 - how is the build reproducible?

I don't know. I tested -8 only on new kernels.

amd64.
Standard vanilla kernels from git. No special flags.

Reproducible: I tried a some kernels with old and new compiler (yes: I 
started to git bisect the kernel). With old compiler I have bootable 
kernel, with new compiler the kernel block at very beginning.

So if you have a hint about what patch should I remove/apply, I could 
check if it solve the problem.
