Subjectswsusp 2.0 with kernel 2.6.4, failure to suspend (vaio fx701)
Hi all, hi Nigel,

as promised I tried swsusp2 with my vaio. Here is my report:

Ok,
I tried swsup2 with kernel 2.6.4. Maybe I have made something
incorrect, so I will simply report what happened to me.

* I have a Sony FX701 laptop; Mandrake 9.2 with upgrades, with
working 2.6.4 kernel. It works (in the sense that it will suspend
correctly) with in-kernel swsusp and pmdisk.

* To test swsusp2, I did the following:
- patched a vanilla kernel with (in the order):
software-suspend-linux-2.6.4-test3-whole.bz2
software-suspend-core-2.0-whole.bz2*
software-suspend-core-2.0.0.22-incremental.bz2*
Configured and installed; .config and lilo.conf available here:
http://perso.wanadoo.es/r_mano/vaio/suspend/dot_config.zip
http://perso.wanadoo.es/r_mano/vaio/suspend/lilo.conf.zip

* Then I used my suspend script, with the only change of
echo yes > /proc/swsusp/activate
instead of
echo 4 > /proc/acpi/sleep
(script is rg_sw2_script)
http://perso.wanadoo.es/r_mano/vaio/suspend/rg_sw2_script

* The result is:
- the laptop switch to text console
- a screen says "waiting to activities to finish"
- I waited 5 minutes, but nothing happened - the "status bar" would not
move.
Pressing ESC at this point, the laptop comes back to its normal working
condition, with the task dump included in the file
failed_suspend1.txt.gz.
http://perso.wanadoo.es/r_mano/vaio/suspend/failed_suspend1.txt.zip

* I rebooted (to have a fresh start) and repeated with swsusp2
debug_level set to 9, log_everything to yes, like this:
# echo 9 > /proc/swsusp/default_console_level
# echo yes > /proc/swsusp/log_everything
# echo yes > /proc/swsusp/beeping
# echo yes > /proc/swsusp/slow
and what I obtained is a very similar behaviour, see it in
failed_suspend2.txt.gz. Now during suspend a few traces were printed (I
am not sure they have been logged, they scrolled really fast) then a
series of lines told "swsusp_num_active is 4, Idle for 250 jiffies"
scrolled away, more or less one or two per second. Pressing ESC will
resume the laptop.

Conclusion: swsusp2 does not work for me, but probably it's a trivial
problem... There is something that would not freeze.
I am available to give more info on request and try more things.
