Odd boot message.

[James T]

I'm running Pardus 2009 with kernel 2.6.30.8-127 on a  HP2133 (VIA processor), and when ever I boot the machine I get the following message:

Code:

Oct 14 10:21:46 ephiny kernel: [    4.314207] longhaul: APIC detected. Longhaul is currently broken in this configuration.

Does anybody know:
a) what it means and
b) if there's anything can be done to get rid of it?

At what point of the startup process do you get this message?

Hi atolboo:

It comes up on the screen right at the start, before "INIT: 2.86 Booting", and is then repeated in /var/log/syslog shortly after the USB and Network subsystems are initialized. (I've added the lines around the occurrence in the log file)

Code:

Hello James,

please have a look in this Wiki

Perhaps that can help you, otherwise you should write a Bug here

If P2009 is running without problems and want to suppress this message add/check the "vga=791" option in
System Settings > Boot Manager (see image below)

Thanks guys.

So I think the summary is that frequency-scaling isn't properly working at least in the stock kernel on VIA C7 processors.

Sometime when I've got time to let the machine do a kernel build I see if enabling the VIA C7 options helps. Is there any documentation on building kernel packages for Pardus (a search for kernel and build in the wiki didn't show anything useful)?

I am not an expert on this subject, so I can't give you an answer.
As far as I know the only possibility is with a bug report.

Hello James,

here the answer of the developer "Ozan": 

--- Comment #1 from Ozan Çağlayan <ozan @ pardus.org.tr>  2009-10-16 10:12:46 ---
This is not a bug. It's warning issued by kernel saying that longhaul driver
will not be enabled on that system because it's not working correctly on that
configuration.

Thanks Bubbel -- I'd not done it because I wanted to investigate a bit more closely first.
