When I run 'halt' the kernel prints:

Power down.
acpi_power_off called

But the system does not shut down. (The fans keep spinning, the LEDs keep shining, the LCD keeps displaying.) Basically, the motherboard is still providing power to every component, as if the power supply had refused to stop.

Kernel is 2.6.22.1-rt9

I followed the instructions given here:

Do you know what could be the problem?
(Meanwhile, I will investigate Remy Bohmer's suggestion.)
