Subject: ICH9 & Core2 Duo - kernel crash

Hello,

I am trying LKML to get some help on one linux kernel related problem.
Lately we got a machine with new HW from Intel. CPU is Intel Core2 Duo E6850 
3GHz with 2GB of RAM. Motherboard is Intel DG33BU with G33 chipset.

After long fight with kernel crashes on different things, we figured out that 
if the multicore is disabled in bios, everything is ok and machine is running 
good. No kernel crashes no problems, but with one core only.

This small table will maybe explain:

Cores   -     kernel   -   state
   2  -   nonsmp or smp  - crash
   1  -  smp or nonsmp  - ok

All crashes have been different (swaper, rcu, irq, init.....) or we just got 
internal gcc compiler error while compiling kernel/glibc/.... and the machine 
was frozen.

Please can somebody advise what to do to identify that problem more precisely.
(debug kernel options?)

Our immpresion - ICH9 & ICH9R support in kernel is bad... sorry to say..
