[SOLVED] Kernel 2.6.36.1 acpi issue.

With the 2.6.36.1-1 kernel from testing there is no /proc/acpi/sleep file. It works fine with 2.6.35.8.

More info later.

Moderator edit - corrected kernel version number to avoid confusion. tomk

Surely we are not going back to 2.6.31?

Re: [SOLVED] Kernel 2.6.36.1 acpi issue.

Just tried with the -3 version. The problem is still there.

The /proc/acpi/ dir with 2.6.35.8-1:

dr-xr-xr-x 5 root root 0 Nov 24 03:59 button
-r-------- 1 root root 0 Nov 24 03:59 dsdt
dr-xr-xr-x 3 root root 0 Nov 24 03:59 embedded_controller
-r-------- 1 root root 0 Nov 24 03:58 event
-r-------- 1 root root 0 Nov 24 03:59 fadt
dr-xr-xr-x 4 root root 0 Nov 24 03:59 fan
-r--r--r-- 1 root root 0 Nov 24 03:59 info
dr-xr-xr-x 4 root root 0 Nov 24 03:59 power_resource
dr-xr-xr-x 3 root root 0 Nov 24 03:59 processor
-rw-r--r-- 1 root root 0 Nov 24 03:59 sleep
dr-xr-xr-x 3 root root 0 Nov 24 03:59 thermal_zone
dr-xr-xr-x 3 root root 0 Nov 24 03:59 video
-rw-r--r-- 1 root root 0 Nov 24 03:59 wakeup

The /proc/acpi/ dir with 2.6.36.1-3:

dr-xr-xr-x 5 root root 0 Nov 24 13:48 button
-r-------- 1 root root 0 Nov 24 13:46 event
dr-xr-xr-x 4 root root 0 Nov 24 13:48 fan
dr-xr-xr-x 3 root root 0 Nov 24 13:48 processor
dr-xr-xr-x 3 root root 0 Nov 24 13:48 thermal_zone
dr-xr-xr-x 3 root root 0 Nov 24 13:48 video
-rw-r--r-- 1 root root 0 Nov 24 13:48 wakeup

Any ideas. I hope that there will be no need for a kernel bisect...

Does anyone knows what module is responsible for /proc/acpi/sleep file?

Give what you have. To someone, it may be better than you dare to think.

Re: [SOLVED] Kernel 2.6.36.1 acpi issue.

I think I found it.

/proc/acpi/sleep was flagged as deprecated (though I could find something relative to the changelog). The replacement is /sys/power/state. So, echo -n mem > /sys/power/state does the trick.

Re: [SOLVED] Kernel 2.6.36.1 acpi issue.

heya,

I've found myself unable to suspend my system - running pm-suspend flashes the screen, but then doesn't do anything else.

Is this particular issue noted here related to it? Does pm-suspend depend on /proc/acpi/sleep? (It shouldn't right, since firewalker mentioned it's deprecated?)

Cheers,
Victor
