please send me "powertop -d" output, as well as the output of
"dmidecode"..... quite possible that that's enough for me to fix this..

Hi, please see the attached powertop-before.out, right before modprobing the processor module, and powertop-after.out right after that, and also dmidecode.out, all on a minimally booted system.

Suggestion: increase the VM dirty writeback time from 5.00 to 15 seconds with:
echo 1500 > /proc/sys/vm/dirty_writeback_centisecs
This wakes the disk up less frequently for background VM activity
