Hej!

I'm running gentoo on my Thinkpad R51e which works real fine. WLAN,
Ethernet, Sound, Suspend to RAM, Video (I only need 2D), etc, no problem.
But I have a hard time optimising life on battery. For starters the switch
from ac to battery doesn't lead to execution of scripts in /etc/acpi :-(

How do I debug this? It seems acpid never reports the switch as event:

Apr 18 08:53:55 asterix acpid: received event "processor CPU 00000081
00000000"
Apr 18 08:53:55 asterix acpid: notifying client 4346[104:443]

Apr 19 08:39:10 asterix acpid: 1 client rule loaded

01:34 was start of suspend-to-RAM and 08:39 the resume. There are never any
other events logged! I've added logger lines to the scripts
in /etc/acpi/actions (from laptop mode) but those aren't executed.

The state variable in /proc/acpi report the switch just fine:

vitus@asterix:~$ cat /proc/acpi/ac_adapter/AC/state
state: on-line
vitus@asterix:~$ cat /proc/acpi/ac_adapter/AC/state
state: off-line
vitus@asterix:~$ cat /proc/acpi/ac_adapter/AC/state
state: on-line

Module thinkpad_acpi is loaded, controlling fan, volume and brightness
works. Where do I start investigating? acpid, hald, thinkpad_acpi?

PS: thing is this notebook can't really save power (celeron-m, atheros w/o
powersave mode), but this is another story.

It's this kernel bug: http://bugzilla.kernel.org/show_bug.cgi?id=8246

I've added ec_intr=0 to my kernel commandline to get reasonable
boot/suspend/resume times and this prevents ACPI events. How do I get
notified when the mentioned patch made it into the mainline kernel? I'm
already in the CC list of that bug.

Bye,
Vitus

Hi Vitus,

Long time, no read! [I presume you are the Vitus Jensen who used to post
on Fidonet. If you aren't, I apologise.]

If you want to get notified by the Gentoo project you need to add a bug
record to Gentoo's Bugzilla, or CC yourself onto an existing record for
that same upstream bug. The URI for Gentoo's Bugzilla is:
https://bugs.gentoo.org/

An alternative is simply to read the change log of whichever kernel
sources you are using. This is accessible from Gentoo's home page
whenever the kernel source code is changed. To ensure the change has
not rolled off the log, you should emerge --sync fairly frequently and
read the change log a.s.a.p. after your Portage tree has a new kernel
available. [My desktop machines do it twice a day, but that might be a
little difficult for a laptop.]

Well, this is Usenet, you can't know who I am, can you? :-)

But you're right, I'm the same guy. Running OS/2 plus LAN Server from
1991-2007 and now nslu plus gentoo. It's not that different as I started
my career with DOS and Minix 1.3. It was on OS2PROG, right? It's a
familiar feeling here: usenet is starting to get as deserted as fidonet :-(

OK, so probably I did the right thing when I added myself to
bugzilla.kernel.org.

Hmm, the Changelog is accessable via
http://packages.gentoo.org/package/s...gentoo-sources so I don't
need to update that often. But as that Changelog is fairly condensed the
best is probably to do a diff.

Is twice a day OK for gentoo mirrors? I thought syncing should be less
often to keep the bandwith usage down? Or is twice a day seldom?


From bugzilla.kernel.org: "I'm seeing the same problem, which isn't fixed
with noapic: Appending ec_intr=0 does indeed shorten the time taken to load
the modules, but ACPI events are not being detected.
(/proc/acpi/button/lid/LID/state is correct however)"

That bug apperently was already fixed, I can boot without ec_intr=0. But
ACPI still aren't reported :-(

Bye,
Vitus

Correct.

I guess the Internet is being swamped with non-technical people.

The more frequently one does an emerge --sync the less bandwidth each
one takes. People who choose to mirror Gentoo completely are suggested
to rsync every 3 hours or so. I guess Gentoo's own mirrors have plenty
of bandwidth these days.
