CPU Frequency Scaling while hibernating

I have pentium D processor, and I tried to enable CPU Frequency Scaling. So, according to the article on archwiki -- https://wiki.archlinux.org/index.php/CP … cy_Scaling , I installed cpupower and did everything that wiki says.

There are two modules that work with my processor -- acpi-cpufreq and p4_clockmod. The first one offers only two frequencies 2.4GHz and 3GHz. p4_clockmod offers much more flexible scaling -- 375 MHz, 750 MHz, 1.13 GHz, 1.50 GHz, 1.88 GHz, 2.25 GHz, 2.63 GHz, 3.00 GHz.

According to https://bugs.launchpad.net/ubuntu/+sour … omments/20 , I changed a little bit the p4_clockmod module in order to make it work, and it worked. But when I tried to hibernate the system, I got the errors in system log:

Apr 28 01:55:05 morfina dhcpcd[402]: eth0: renewing lease of 10.0.21.81
Apr 28 01:55:05 morfina dhcpcd[402]: eth0: acknowledged 10.0.21.81 from 192.168.22.2
Apr 28 01:55:05 morfina dhcpcd[402]: eth0: leased 10.0.21.81 for 300 seconds

As you can see, there are plenty of nouveau errors, and of course the graphic environment couldn't be loaded. System hangs. I thought that this could be related only to nouveau driver, and not to p4_clockmod module, so I installed nvidia graphic drivers and tried to reproduce this behavior. But I couldn't.

I can't use nvidia drivers for now, so the question is: is there any solution that could fix this issue, or do I have to give up on the  p4_clockmod module?
