No core dump is produced, the screen remains steady. This can only be terminated by a hard power off. Not running powerd seems to avoid the problem. Note 1: Before completely freezing, the machine from time to time hangs for from a few tenths to several seconds. After such a freeze, "xload" shows a sharp spike from near zero to approx. 1.5..2 load which subsequently decays exponentially. Note 2: At the end of last December, I tried to upgrade this machine to 8.1 amd64. This produced totally unstable behavior/crashes, most likely also related to the video driver. At that time, I did not yet suspect cpufreq/powerd. The machine uses the following graphics controller: vgapci0@pci0:0:2:0: class=0x030000 card=0x13f710cf chip=0x2a028086 rev=0x03 hdr=0x00 vendor = 'Intel Corporation' device = 'Mobile 965 Express Integrated Graphics Controller' class = display subclass = VGA vgapci1@pci0:0:2:1: class=0x038000 card=0x13f710cf chip=0x2a038086 rev=0x03 hdr=0x00 vendor = 'Intel Corporation' device = 'Mobile 965 Express Integrated Graphics Controller' class = display The chipset is ICH8. >How-To-Repeat: See the description above. Generally, this cannot be reproduced easily, however, the machine will crash within seconds to hours from starting X. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
