Subject: Widespread boot failures on ARM due to "mm/page_alloc.c: calculate zone_start_pfn at zone_spanned_pages_in_node()"
Date: Mon, 4 Jan 2016 22:42:33 +0000 [thread overview]
Message-ID: <20160104224233.GU16023@sirena.org.uk> (raw)
[-- Attachment #1: Type: text/plain, Size: 1155 bytes --]
Since 20151231 -next has been failing to boot on a wide range of ARM
platforms in the kernelci.org boot tests[1]. Doing bisections with
Arndale and BeagleBone Black identifies 904769ac82ebf (mm/page_alloc.c:
calculate zone_start_pfn at zone_spanned_pages_in_node()) from the akpm
tree as the first broken commit[2,3]. An example bootlog from the
failure is:
http://storage.kernelci.org/next/next-20151231/arm-multi_v7_defconfig/lab-cambridge/boot-exynos5250-arndale.html
which shows no output on the console once we start the kernel, a brief
sampling of failing boards suggests this is the normal failure mode.
x86 and arm64 targets seem fine (juno shows up as failing but the boot
log seems fine so it's probably a false positive, Mustang was failing
already) and there are a small number of ARM platforms that boot. I've
not yet had any time to investigate further than that (including trying
a revert of that commit), sorry.
