Subject: [x86, kaslr] Initramfs unpacking failed: junk in compressed archive
Greetings,
I got the below dmesg and the first bad commit is
commit 82fa9637a2ba285bcc7c5050c73010b2c1b3d803
Author: Kees Cook <keescook@...omium.org>
AuthorDate: Thu Oct 10 17:18:16 2013 -0700
Commit: H. Peter Anvin <hpa@...ux.intel.com>
CommitDate: Sun Oct 13 03:12:19 2013 -0700
x86, kaslr: Select random position from e820 maps
Counts available alignment positions across all e820 maps, and chooses
one randomly for the new kernel base address, making sure not to collide
with unsafe memory areas.
