Most people using Centrino seem to be reporting similar things. You
might want to swap it for a more Linux friendly laptop if you really
need ACPI stuff or working wireless

Samsung X10 XTC 1300

[Nicolas Bellm]

Hello!
I have a Samsung X10 XTC 1300 with Intel Centrino. I downloaded the 
kernel-2.4.20 and patched it with 2.4.21-rc1 and the ACPI patch. I compiled 
and loaded all modules for ACPI. But I can't get it in the sleep-mode. I 
tried 'echo 1 > /etc/acpi/sleep', I tried echo 2, 3, 4, 5 ... and echo P1-P5, 
but it doesn't work. It doesnt react, when I press the powerbutton. I can't 
change the processor speed, I can't read the battery loading. Nothing works.

indeed <sigh> i have had CPU scaling working with CPUFreq on my dell
D600 (Dell is rapidly becoming the Ikea of computer vendors :) but the
same problems with ACPI sleep. (S1 works, S3 doesn't, although S5 does)

when ACPI does work then when bus modules are loading i get a lot of: 

dsobject-0189: *** Warning: Buffer created with zero length in AML

this is using the ACPI4Linux patches against 2.4.20 and  2.4.21-rc1

ACPI didn't load at all in 2.4.21-rc1-ac2 though (i don't have the exact
message to hand, but something about signatures being incorrect maybe) 

i have settled on a reasonable compromise of using swsusp with ACPI on
2.4.20 (using a patch from http://alor.antifork.org/acpi-swsusp/) which
is acceptable and works (i think you need at least S5 to work for swsusp
to turn the machine off)  

/proc/acpi/processor/CPU0/performance reports the requisite number of P
states but the associated CPU speed for all of them is 0Mhz 

also weirdly i can change the P state from P0 but only to P5 or P6 and
then i can't change it back again (although this doesn't seem to have a
great deal of effect) 

throttling  changing works (i.e. the T state changes) but i'm not
entirely convinced it is actually doing anything. 


owen

I'm facing this kind of decision (buying a new laptop soon, possibly the
Toshiba DynaBook SS S7/290LNKW) -- so, does the above mean that Intel
Centrino is not Linux friendly?

Andy, Bob, could you please comment on this?

I've already ruled out all Compaq notebooks thanks to the multiple
problem reports seen on this list (hi HP/Compaq! congratulations on the
market strategy), but I had thought all Centrino-based notebooks would
be among the better supported ones?

More specifically, if I can add my $0.02 here, are these problems due to
the general lack of support for the platform, or just mediocre DSDTs?

I think that's awfully short-sighted.  Compaqs appear, from my reading of this
list, to be some of the better supported laptops.  Sure there are lots of
niggling little problems, but most of them can be fixed - thanks to the support
available here from both users and HP.  Now, if Dell would only provide some
support....

Currently yes. On some of them the APM works well enough to suspend and
do battery reporting but not to do CPU speed control stuff (at least not
from battery life measurement).

The newer Compaq ACPI seems to work well (eg the z9xx series laptops).
They do need an ACPI kernel and have some other quirks which needed
Linux fixing (and which showed up Linux bugs too)

Having used Compaq laptops for a long time (since first PII-350 model
of the Armada M700 and every model since in the M700 series and now
the Evo N800c), I'd say that these laptops are generally working very
nicely with linux. Even ACPI, which looked dire a while back, now
works like a charm with the Evo I have, and run Linux as the host OS
on it 98% of the time, the other two are spent in XP playing Ghost
Recon ;)

As is being discussed in another thread here, are the issues of how to
be able to roll your own custom DSDT into a kernel more easily, to
make ACPI work more readily for a wider audience.

mvh,
A

Is it? From what I see, people have to fix and patch their DSDTs in
order to get their notebooks working. I didn't have to do that with my
Sharp and I'm not looking forward to the experience. I would like to buy
a notebook that I can boot Linux on without going through the hassle of
ironing out the details.

But I guess everyone's taste is different. The level of "acceptable
annoyance" is also different for each one of us.

But I didn't see any comments from Andy or Bob in this thread -- about
Linux and Centrino, which is what this thread is really about?

Andy have already answered this in the cpufreq mailing list (at least
for CPU frequency stuff).  Basically, a binary only driver for the
enhanced speedstep stuff is already available (look at intel site.
Don't rememeber exactly the URL), but documentation about this
technology will be done (well... I hope it will done).
