Bug#601948: linux-image-3.2.0-2-686-pae: Fails to resume from hibernate (all pm_test modes pass)
Package: linux-2.6
Followup-For: Bug #601948
Hi. I'm also suffering from this on linux-image-3.2.0-2-686-pae, HP
ProBook 4515s. The behaviour is exactly the same. It looks like the
kernel *doesn't even try* to resume from the file on the filesystem
(BTW: how does the kernel know from where to resume? I have never
understood that; it's a kind of magic for me).
I also have run all the tests Documentation/power/basic-pm-debugging.txt
and all the /sys/power/pm_test tests work fine. The ones with "echo
platform > /sys/power/disk" and "echo disk > /sys/power/state" don't
run, obviously, as the kernel doesn't try to resume from the filesystem.
Running with init=/bin/bash gives the same: "bash: echo: write error: No
such device".
Suspend-to-RAM and resume from suspend works fine.
I remember that hibernation worked in the past, but I haven't used it
for some time because I mainly keep my laptop connected to the AC and I
use Suspend-to-RAM alot. Now I was curious to check if hibernation works
and... bummer.
