This method doesn't work at all. What I can see is that the following
line is displayed:
swsusp: Cannot find swapdevice, try swapon -a
"swapon -a" works just fine. "swapon -s" shows me that the swap partition
is in use.
The effect of the suggested commands is that the command just returns
back to the console with the following message:
# echo 8 > /proc/sys/kernel/printk
# echo disk > /sys/power/state
bash: echo: write error: No such device
#
I don't know if the following information is of any help: The HOWTO talks
about the necessity to configure the swsusp swap device at the compile
time of the swsusp userspace tools:
[...]
(e) Configure, build and install the suspend utilities
- Edit Makefile and the conf/suspend.conf file to reflect the
configuration of your system (please refer to Section II of this
document for details). The value of the RESUME_DEVICE constant in
Makefile must be the same as the value of the "resume device" parameter
in the configuration file and it must be the full path of a swap
partition device file (eg. /dev/hda3).
[...]
I don't know what magic Debian's uswsusp package is using, but aparently
this step is not necessary there (?), as it's only using a config file
which Debian's s2disk accesses and the initramfs image is generated in
such a way that this setting is transported in it and resume just works as
well.
