I've started my kernel 2.5.18.
I was testing software suspend, but kernel said:

Kernel Panic: pse required

Software Suspend is not posible now.

But i was able to continue, now I've pdflush running on PID 6,
and it takes 100% of idle cpu, perhaps it has nothing to see with
Software Suspend.....

if it's needed, info from proc: (.config and dmesg attached)
