So, it does seem like > something is not quite in cpufreq > RELENG_7_0... My experience with my T43 (not T43p) is that it does not play well with cpufreq. This is not new to 7-Stable. I have been seeing it since the system was new, just over 2 years ago. I always build my kernel without it. Aside from the sort of thing you saw, I also saw misbehavior in switching between battery and AC and powerd did odd things. Without cpufreq, it runs well in all respects. dev.cpu.0.%desc: ACPI CPU dev.cpu.0.%driver: cpu dev.cpu.0.%location: handle=\_PR_.CPU_ dev.cpu.0.%pnpinfo: _HID=none _UID=0 dev.cpu.0.%parent: acpi0 dev.cpu.0.freq: 2000 dev.cpu.0.freq_levels: 2000/27000 1750/23625 1600/22600 1400/19775 1333/19666 1166/17207 1066/16733 932/14641 800/13800 700/12075 600/10350 500/8625 400/6900 300/5175 200/3450 100/1725 dev.cpu.0.cx_supported: C1/1 C2/1 C3/85 C4/185 dev.cpu.0.cx_lowest: C1 dev.cpu.0.cx_usage: 100.00% 0.00% 0.00% 0.00% -- R.
