I made the above modification and boot. I see some debug statements during boot but I cannot copy them since the system hangs subsequently during IDE setup as I have written previously. If I compile the processor as a module and do modprobe after full boot, then system hangs but I dont get any debug messages in /var/log.

Hello
I will add some more info that I could read. I dont know how to copy them so am typing them myself. I compiled processor/thermal as modules and did modprobe after full boot. I kept an xterm open with "cat /proc/kmsg" and did "modprobe processor" in another xterm. I was then able to see the debug messages in the first xterm.

Processor module hangup on R40e
The problem is with processor power management.
In function acpi_processor_add
/*
* Install the idle handler if processor power management is supported.
* Note that the default idle handler (default_idle) will be used on
* platforms that only support C1.
*/
pr->flags.power=0; //My addition to disable power management <=======
if ( (pr->id==0) && (pr->flags.power) ) {
pm_idle_save = pm_idle;
pm_idle = acpi_processor_idle;
}
With this modification the processor module does not hang. Thermal can also be loaded and gives correct temperature. I would still like to know why the power management is causing problem and what are the implications of disabling it the way I have done.
Thanks
