Subject: [stable] KASLR could not find suitable E820 region...
Date: Tue, 25 Nov 2014 11:14:16 -0800	[thread overview]
Message-ID: <20141125191416.GA4648@wfg-t540p.sh.intel.com> (raw)

Hi Kees,

We noticed the below boot errors in stable kernels 3.16.7 and 3.17.2
on real hardwares:

        early console in decompress_kernel
        KASLR could not find suitable E820 region...

        Decompressing Linux... Parsing ELF... Performing relocations... 

        32-bit relocation outside of kernel!

These kconfig options are enabled:

        CONFIG_RANDOMIZE_BASE=y
        CONFIG_RANDOMIZE_BASE_MAX_OFFSET=0x40000000

Before digging further, we'd like to ask for a quick answer that
whether they've been fixed by some commit in current mainline kernel?

Thanks,
Fengguang
