so i had a look - it IMHO is a firmware/kernel bug to not into deepest sleep
state if the cpu happens to be eg. in performance mode etc. etc. - suspend
should suspend to the same state regardless of state of the cpu before suspend.

i put a workaround where e will lower it to the lowest power state before
suspend (then reverse on resume), but the problem may still happen. something
else other than e may cause the cpu to flip to a performance (for example) mode
and thus cause the problem again - and it is not e doing it then. the kernel
IMHO *SHOULD* at suspend time after all userspace processes are frozen, force
the processor to a lower power state if this would prevent lowest power suspend
and then continue suspending.
