Known bug there has been there for ages so this is not a regression.
I suggest removing it from this list - and I will see to have
it fixed for 2.6.24.
I will not push any fix for -rc for this.

Can you try unloading acpi_cpufreq? I seen similar bug in suse
kernel...

If that does not help, try unloading as many modules as possible...
