Package: src:linux
Version: 4.9.30-2
Severity: important
Tags: upstream
Hello.
It looks like I found a problem in the kernel that is currently shipped with
debian stretch.
In the stretch kernel ASLR mechanism got enabled (kernel option
CONFIG_RANDOMIZE_BASE), which conflicts with the hibernation mechanism
(kernel option CONFIG_HIBERNATE).
It is clearly stated in the CONFIG_RANDOMIZE_BASE help that enabling
KASLR will prevent kernel from hibernating, cite:
If CONFIG_HIBERNATE is also enabled, KASLR is disabled at boot
time. To enable it, boot with "kaslr" on the kernel command
line (which will also disable hibernation).
Unfortunately, in my case it is not disabled. That is, I'm able to
hibernate, and then, when I turn on my laptop (Thinkpad X220i) again,
kernel tries to restore the dump it made while hibernating, fails, and
that leads either to hard reset of the laptop, or just it turning off.
I've spent around a week trying to find out why my hibernation doesn't
work. I suppose that, if KASLR is enabled (i.e. by default) the kernel
should disable hibernation *and* drop a message into dmesg that it can't
hibernate because of KASLR.
I'm pretty sure that it is an upstream bug, so I mark this report as
upstream. I also tried 4.11 kernel from the unstable branch -- situation
is the same.
