[solved] grsecurity-3.1-4.4.3-201602282149 unable to boot

Sorry to say, the new grsecurity-3.1-4.4.3-201602282149.patch is only working on virtual hosts.

Kernel is crashing in a very early state:

1. can you post the full picture (some important parts were cut off)?
2. does it fail in qemu?
3. can you post your config and vmlinux?

1. this is all I can get. First time booting with this kernel hangs on loading the ramdisk.
The picture is after the second boot:

2. this is happening on 2 hosts. Quemu based VM's are running well with the newest grsecurity patch.
The picture is from my desktop system. On my server the last message I can see is something with ACPI and reboots afterwards. (my TFT is to slow)

3. I'll send you with pm

sorry I missed:
gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04.1)
Ubuntu 14.04 64bit

The latest grsecurity patch "grsecurity-3.1-4.4.3-201603012143.patch" fixed the kernel crash while booting system!
