Hi there

I followed this howto:
http://www.thinkwiki.org/wiki/Installing_Ubuntu_6.10_%28Edgy_Eft%29_on_a_ThinkPad_T60#Problem:_Hibernate_.28Suspend_to_Disk.29_does_not_work.21
(on Feisty) and now my one CPU is stuck in 'performance'. On
investigation I see that cpu1/cpufreq is a symlink to CPU0:
<pre>
$ ls -l /sys/devices/system/cpu/cpu1/cpufreq
lrwxrwxrwx 1 root root 0 2007-05-21 12:37
/sys/devices/system/cpu/cpu1/cpufreq ->
../../../../devices/system/cpu/cpu0/cpufreq
</pre>

Would it be safe to 'rm -r cpu1/cpufreg && cp -r cpu0/cpufreq cpu1'  ?
Is this symlinking a misfeature that should be reported at
https://bugs.launchpad.net/ubuntu/ ?
