on bug 72921
from Kertesz Laszlo
I activated bapm on my A8-6500 (on a GA-F2A88X-D3H mobo). It is working as advertised - the CPU reached its 4GHz turbo core speed and was working between 3.5GHz(nominal top speed) and 4GHz for quite long time periods. Actually, from a performance point of view, this is the best so far (Catalyst had some nasty CPU slowdowns, not seen in /proc/cpu). Now, the problems - about once a day the computer reboots suddenly. Every time my wife was playing some flash based Facebook game BTW. Using other stuff, even playing 3D games or using VDPAU acceleration didnt seem to create problems. Also, i observed this in the system log: [ 299.812285] mce: [Hardware Error]: Machine check events logged /var/log/mcelog has these: mcelog: failed to prefill DIMM database from DMI data mcelog: Unknown CPU type vendor 2 family 15 model 3 Hardware event. This is not a software error.
