standby resumes immediately in 2.6.0-test8

standby resumes immediately in 2.6.0-test8

[Aviram Jenik]

Hi,

I am trying to get "standby" to work on my Sony vaio laptop. I did:
echo -n "standby" > /sys/power/state

But this only flashes the screen once (in X this is more noticeable) and 
resumes immediately.
Dmesg shows:

PM: Preparing system for suspend
Stopping tasks: 
============================================================================|
Restarting tasks... done


I am using 2.6.0-test8 with suspend and sleep states enabled. All other ACPI 
functions seems to work fine, my laptop is an R505DL.

How can I debug this?

You might try

sleep 1; echo -n "standby" > /sys/power/state

I have the feeling that the "release key" event othe return key wakes the
computer up. With the sleep 1; the "release key" event occurs while the
computer is not yet suspended.

That might be considered a bug, by the way.

I tried it, but that didn't help. I even booted with init=/bin/sh to make sure 
nothing is running (and no modules are loaded) and tried the line above  - 
again the resume was immediate.

It *does* look like something wakes the computer up immediately - but what can 
it be?

Could you please do

# echo -n standby > /sys/power/state
# echo $?

and report whether that says '0' or '1'? 

Also, please send the output of 'cat /proc/acpi/sleep' ? If "S1"  is not
present, then your system does not support standby, and it will not work. 
Otherwise, we truly do have a bug..

Thanks,

	Pat

I guess not :-(

For the record, it's a Sony Vaio R505DL.

Is there a certain reason why

# echo standby > /sys/power/state

(also without -n) is not accepted by the code?

Bas.

It's just pedantic about the parsing, which saves a couple of lines of
code. If it's too inconvenient, please use a script to mask it. :)

Wow, could you please post patches to the list? You get very little
exposure for fixes posted solely through bugzilla, which means your effort
goes wasted.

Ditto for dialog about bugs. I don't track bugs there; I consider the 
mailing lists to be the proper forum for doing so. If you or someone else 
would like to add play-by-play commentary there (or vice versa) that might 
be helpful.. But they might otherwise go unnoticed.

Thanks,


	Pat

It's pretty strange that OSDL goes to the trouble of setting up a bugzilla, and you want people to do things the old way.

I think the general consensus is that email is not a good bug tracking system. However, you can subscribe to acpi-bugzilla if you really want visibility into acpi bug updates through email.

You of all people should know that the efforts of some parts of the
company do not reflect the opinions of some of the individuals of that
company.

FWIW, OSDL did not set up the bugzilla database; it simply donated
hardware and are hosting it. AFAIK, it is maintained by a group of
developers at IBM.

Posting patches solely to a bug-tracking database eliminates the 
possibility of review or feedback through the traditional means - email. 
It severely limits visibility to the people that actively track the 
database and/or subscribe to yet another splinter list. 

Many people are not willing to do that because it adds unnecessary steps 
to the review process or simply because they do not have time.

Ugh. *Another* list? All I want to do is see the patches. What's so hard 
about posting them to acpi-devel or linux-kernel?

I think you're just complaining because it's fun.

If you really have an issue, please report it via bugzilla. ;-P

Well, that an issue for me as well.  I would much be able to
get patches from a mailing list.  Unfortunately, bugzilla
do not send patches to the bugzilla acpi mailing list, and
that is the main concern for me.  I will therefore
unsubscribe to the bugzilla mailing list now.
