My system Kernel Panic frequently last times

[overshoot]

Hello,

 

Here is the last message taken from logs just before my system panics (i was installing a new package and it happened just after clicking "finish" from the installer) :

 

4/15/09 2:55:56 PM kernel RpcOut: couldn't open channel with RPCI protocol

 

 

Last changes i've made were to add Chameleon 2 rc431 and a new Airport card (Broadcom BCM4328).

 

My system is Dell XPS1530 notebook with a C2D T9300, 4GB. The leopard version i'm running is the 10.5.6.

 

 

If someone has an idea of what cause this... thanks in advance.

 

Regards,

Julien.
