I have been using cpufreq on and off since this got comitted and just noticed a problem now. I can't really say when it started happening, but I can say that it happens with a current from about 2 hours ago. What happens is when I kldload cpufreq, usb stops working. If I have a device that was already connected, it gets disconnected, I am unable to connect any new devices. It's just completely unresponsive. Whatever the issue is, it does not help to kldunload cpufreq, I am forced to reboot to get USB working again. The system is an IBM Thinkpad R40. I can give you whatever relevant info you need on request. -- If I write a signature, my emails will appear more personalised.
