Strangely, it only breaks when using the Alt-SysRq-O poweroff function. Shutting down normally still powers off the system (and does print 'acpi_power_off called'). I think it must have something to do with the IDE devices not having powered down before acpi_power_off is called, but I haven't seen the code so I have no idea what really causes it to break.
