Bug description:
My system:
Dell Vostro 1400
Intel Core 2 Duo @ 2.0 GHz
3 GB Ram
1 GB Swap
I recently got suspend & hibernate working on my system by modifying
the hal scripts to use acpi-support sleep.sh and hibernate.sh instead
of powersaved. Now, however, I have found a bug regarding the suspend
and resume scripts:
When I resume from a suspend (suspend to ram, in particular),
/proc/cpuinfo reports that CPU1 is running @ 1994 MHz. Further
investigation reveals that /sys/devices/system/cpu/cpu1/cpufreq is
gone entirely (It normally is a symlink to cpu0's cpufreq directory).
If there's any extra info I can provide, I am more than willing to.
