Dunno for alexey, but for me it causes my machine to go in thermal shutdown quite soon. Even switching to ondemand doesn't work as the machine keeps running at 100% speed until the temp is too high and the ACPI commands to shutdown because the CPU is too hot. I now have a script I run that monitors the temperature and switches between ondemand and powersave (runs at 800Mhz fixed frequency) states, so that if temp is too high it slows everything down untill temp comes back down to a cool 60C. Even with my script that does just simple polling every few seconds, sometimes I still suffer from thermal shutdwon due to the fact the kernel is too dumb to understand it has to trhottle when temp is too high. This didn't happen on F15 (samba hardware) so I guess we will have happy F16 users very soon :-/ Simo. -- Simo Sorce * Red Hat, Inc * New York -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
