Subject: Kernel panic at boot with ondemand governor as default (2.6.24-rc2)

Hello,

I've tried kernel 2.6.24-rc2 and I have a problem with the new option 
for setting up the cpufreq ondemand governor as default: a kernel panic 
happens early at boot time. If I boot first with performance governor 
and later change to ondemand, everything is fine (as usual).

This seems related to the delayed_workqueue. The kernel panic message 
finishes by:
EIP: [<c012aa60>] wq_per_cpu+0x0/0x10 SS:ESP 0068:c191be58
Kernel panic - not syncing: Attempted to kill init!

A picture of the whole message is available here:

My computer is a x86 using speedstep-ich, and you can find the full 
.config leading to the panic attached.

Does anyone has any idea was it going wrong?
Thanks,
Eric

PS: I haven't tried 2.6.24-rc1.
