That will be fine.

ok i'm testing it now;

if it will work as in your opinion what i've to do? 

have i to give you some others output? what additional information are useful ? 

ok i've tested some hours and it seems a regression of the 2.6.27;

but what to do now to be sure and to individuate the exact problem ? 

give to me all the instructions you need.

thanks

Thanks for testing, I'm adding this bug to the list of recent regressions.

If it's 100% reproducible, I think you can try to use git bisection to identify the commit that introduced the problem.

Hi, Giovanni
    Do you mean that the box can work well on 2.6.26.5 kernel while it fails on 2.6.27-rc7 kernel? right?
    Will you please attach the output of acpidump?
    Will you please try the following boot option and see whether the system can work well?
    a. idle=poll
    b. processor.max_cstate=1(processor should be compiled as built-in kernel)
    c. nolapic_timer
    d. nohz=off(disable tickless feature)
    Thanks.

ok i will try in the week-end;

in the last week the problem seems solved automagically, but i dont think it so much cause of the random factor.

thanks

giovanni, any update?

mmm ... now i'm using 2.6.28-rc2-git3 and i did not have any freeze... 


i did not have system freeze but sometimes the acpi stop to work with some errors like:

ACPI Exception (evregion-0419): AE_TIME, Returned by Handler for [EmbeddedControl] [20080926]
ACPI Error (psparse-0524): Method parse/execution failed [\_SB_.BAT0._BST] (Node f701be40), AE_TIME
ACPI Exception (battery-0360): AE_TIME, Evaluating _BST [20080926]


or like

acpid: executing action "/etc/acpi/default.sh battery BAT0 00000080 00000001"
Oct 29 18:00:38 infectedsynapsis logger: ACPI event unhandled: battery BAT0 00000080 00000001
acpid: action exited with status 0
acpid: executing action "/etc/acpi/actions/lm_battery.sh battery BAT0 00000080 00000001"
ACPI: EC: missing confirmations, switch off interrupt mode.

ACPI Exception (battery-0310): AE_ERROR, Evaluating _STA [20080926]



can you give information about the test to do on this kernel?
what information do you need? 

thanks

Please attach the output of acpidump as requested in comment #10.

acpi dump output on sony vaio sr19xn

I think this latter issue is the same EC problem as reported by Darren Salt on the acpi-devel list.  It was confirmed fixed by

Patch: <http://marc.info/?l=linux-acpi&m=122514341319748&w=4>

no. :(

i'm using 2.6.28-rc4-git5 on a sony vaio sr19xn and the proplem persist :(

Rafael, what does this last post mean?

thanks

This is for the tracking of regressions, who should be sent the automatically generated messages (in addition to the reporter etc.).

Any Update?

I continue to have the problem on 2.6.28-rc5-git4;

Can i help you doing some tests? 

the problem still exists in the latest git tree?
I don't know the recent updates of ec driver.
re-assign to Alexey. :)

Ignore-Patch : <http://marc.info/?l=linux-acpi&m=122514341319748&w=4>

Giovanni, please check 2.6.28-rc7, it contains some important ACPI fixes.

Thanks Rafael. I'm testing this importans ACPI fixes.

At the moment i did not have the error, but instead I got a lot of other problem =) the battery indicator sometime says me i've 0.1hour of battery [when the battery is fully charges.. sometimes it says that i've 10h of autonomy [when i've 4h max]

do you need some information ?

Fix ACPI battery regression

Please check if this patch on top of 2.6.28-rc7 fixes the ACPI battery times problem.

ok now i'm goin to test it.

with the git 3 i get always: 

ACPI: EC: GPE storm detected, transactions will use polling mode
ACPI: EC: missing confirmations, switch off interrupt mode.

Giovanni,
Is this battery issue still present in 2.6.28-rc8?

Linus reverted some commits to battery.c for that release.

the remain battery information is now fixed [reverted]

but i always get this:

ACPI: EC: missing confirmations, switch off interrupt mode.
ACPI Exception (evregion-0419): AE_TIME, Returned by Handler for [EmbeddedControl] [20080926]
ACPI Error (psparse-0524): Method parse/execution failed [\_SB_.BAT0._BST] (Node f701be40), AE_TIME
ACPI Exception (battery-0359): AE_TIME, Evaluating _BST [20080926]

Please file another bug report for this issue.  I'm closing this one since the original problem appears to have been fixed.
