On my fully up-to-date Inspiron 1420 running Hardy, this bug is NOT
fixed. After resume from suspend-to-ram:
$ ls /sys/devices/system/cpu/cpu1/
cache cpuidle crash_notes online thermal_throttle topology
Note the absence of the cpufreq directory. Also, I still get the same
errors in dmesg when resuming:
