I'm testing 3.2.7 right now. I'll have it up soon.

@pipacs, I've had reports of 3.2.2-r1 kernels having problems booting.
idl0r gave me a bzImage which will not boot in qemu. Using the same
kernel config, 3.2.7 *will* boot. The problem occurs shortly after
decompression but before any early printk. Is this a known issue that
has been fixed or should I continue to try to isolate the problem? As I
said it seems to be gone in later kernels.


our hardened-sources-3.2.2-r1 = grsecurity-2.2.2-3.2.2-201201272014

the 3.2.7 which I will put up in a bit is the very latest which came out
today.

hmm, i don't recall such issues but if you can get me a bzImage and vmlinux
i can take a look and tell you what it is.
