CPU Package power limit notification
I recently bought a Toshiba A665-S5187, which has the new i7-2630QM Sandy Bridge Processor. My dmesg output is a bit strange, and I see messages that I am not sure what to think of. I am using kernel version 2.6.39-3-generic.
Code:

I also get this message:
Code:
[ 53.150123] [drm:pch_irq_handler] *ERROR* PCH poison interrupt
I have the CPU Frequency Scaling Governer set to Conservative, if it makes any difference.
What does this mean? The system does not kernel panic or anything, but I would like to know why I am getting these strange messages. Thanks!

Re: CPU Package power limit notification
Hi, do not know, but it does not look good. You could have a failure coming on, or it may be the kernel you are using, you know that is the one for testing it is not meant to be used for a production machine.
Re: CPU Package power limit notification
I am seeing the exact same thing with a thinkpad with the same chip...
using
Linux laptop 2.6.39-0-generic
I don't know what to think either but it's kinda freaking me out.
Maybe it's bogus? See this bug report. I got some of these while it was idle and cool. But some I got while compiling (as a test) so i'm not sure..
Re: CPU Package power limit notification
The same here on Asus X53S with i7-2670QM.
Code:
mcelog: failed to prefill DIMM database from DMI data

I have Ubuntu 11.10 (3.0.0-16-generic) and have some random crashes (may be related to chrome). On Windows 7 I don't see any problems.
Re: CPU Package power limit notification
I'm getting the exact same thing on my MainGear ex-L 15 (i7-2760QM). Of course, I also run Folding@home 24/7, and that keeps my CPU at 100%, but this is a gaming laptop, and is built to withstand huge CPU load. However, I'm pretty sure I get this same error even when the CPU is idle.
The output of "uname -a" is:
Code:
Linux kubuntu 3.2.0-25-generic #40-Ubuntu SMP Wed May 23 20:30:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
I've never had any problems with overheating, I've never had a kernel panic (well, I did once when I tested a fork-bomb on my computer), and I haven't overclocked/overvoltaged it at all.
I don't really worry about it, but it is starting to concern me, because this is a $3,000+ laptop...
Re: CPU Package power limit notification
Isn't there a power bug in the kernel about the sandybridge processors that have them running at full capacity all the time. Maybe this has something to do with your problems.

Re: CPU Package power limit notification
Some problem here with 12.04 on a Lenovo X220 laptop. I get a series of messages like this every five minutes:

The computer is behaving normally and I would not have noticed if I did not snoop into the syslog. The kernel version is:

Re: CPU Package power limit notification
Same thing here with a Toshiba Portege, Intel i5-2467 Sandybridge. Get the message every forty or sixty minutes. I'm sure it's nothing to worry about: my CPU is perfectly cool, running at low speed. What really annoyes me is that this message jumps into my tty and garbles the console, messing up whatever task I was doing.
Does anyone know how to prevent these messages from bothering me in the tty console?

Does anyone know how to prevent these messages from bothering me in the tty console?
Lucky! I get it every couple minutes! It also completely fills up my syslog.
Re: CPU Package power limit notification
Hey guys, I am starting to get the same thing on my laptop. I installed psensor and it turns out my 4 cores run at 51-53°C each when IDLE (that's about 130 F).
I get the messages when booting. When I then turn the PC off and reboot, everything is fine.
It's an Intel Core i7 - 2670QM at 2.2 GHz.
How are you guys dealing with this?
