I updated to BETA-3, disabled all unnecessary modules (sound, net, wifi, ahci), boot in single user (no tricky programs, no external influence) and left laptop for 12+ hours, when I returned LA: 0,62 0,74 0,72 Anyone else observed something like that? If I boot from another flash with 8-STABLE from june, after a few hours I get LA: 0,01 0,00 0,00 , as expected. -- Adios
