3.17-rc1 Crash during hibernate/resume, OOM failures
I own several Haswell based PCs with MSI-7817 chipset, i5-4570 CPU and 8G RAM.
On all of these, before 3.17rc1 I had the problems described in <a class="bz_bug_link
bz_status_VERIFIED bz_closed"
title="VERIFIED FIXED - [HSW Bisected]WARNING: SPLL already enabled"
href="show_bug.cgi?id=78424">Bug #78424</a>.
Since 3.17-rc1 (commit 09fcefee..), the symptoms changed:
* No more WARNING: messages upon resume
* Multiple resumes work fine, but:
* About one in every fifth resume the machine grinds to a halt with various
errors (OOM killer or ext4 related functions in the backtrace or ...)
Setup:
* Ubuntu 14.04 LTS, Kernel 3.16.0+ (3.17rc1 as of now)
* MSI-7817 chipset with i5-i4570
* Boot Lubuntu desktop
* start "make -j4" in the above git checkout
* start Firefox with Youtube video
* hibernate and resume in a loop
I attached dmesg output of a few cases. Also, just today I got the following
via netconsole after five successful hibernation/resume cycles:
