Description of problem:
Hi,

sorry for the lack of precision in this report: I am just a non-coder trying to get my system stable.

I am using sme7 beta (www.contribs.org), which uses centos4 under the hood.

on certain via -epia mini-itx chipssets the system freezes quite randomly.
People report that this behaviour has to do with :
- turn off powersaved. (chkconfig powersaved off)
-  All 2.6 kernels are stable as long as powersaved is turned off and the longhaul module is not loaded

see
http://forums.viaarena.com/messageview.aspx?catid=28&threadid=68832&enterthread=y

Is this code active in the kernel I am using:
kernel-2.6.9-11.EL? 
I see no /proc/longhaul dir.

If it is included in that and centos 4.2 kernel, is it possible that you produce a kernel version with this code disabled, or only compiled in as a module, so that via users can have a stable system? 

See for more information on the bugs the via arena linux forums at:
http://forums.viaarena.com/categories.aspx?catid=28

Please let me know if you need more information.



Version-Release number of selected component (if applicable):
kernel-2.6.9-11.EL

How reproducible:
Didn't try

Steps to Reproduce:
1.I just run my server, which has a busy website and about once a week it hangs.
This is very random.
2.
3.
  

Actual Results:  The system hangs. The keyboard does not give repons, there is no repons to ping. 
The harddisk that usually makes some small sounds all the time stops doing that.
The lights and leds of the system are normally on, there has been no reboot. Nothing is in the mesasages files about it. I can see in my RRD's that nothing special happened before a lock-up. RRD's go blank by the way.

Additional info:


I have a via epia pd with cpu 600mhz fanless.
