| |
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. http://perso.wanadoo.es/r_mano/vaio/suspend/failed_suspend2.txt.zip 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.
