I used to have this exact problem. I solved it by forcing the ospm_system
module to load at boot time, by mentioning it in /etc/modules.
is part of ACPI; on your system it might be a different module, e.g. if
What seems to happen is that at power down, the last thing the kernel
to do is to call ospm_system to turn the power off. But the kernel module
loader has already been shut down, so if the module hasn't already been
loaded, it can't load and the kernel hangs.
I had this problem with the 2.4 kernels, but I believe it's been solved in
2.6. I'm running 2.6.0-test4, and now that I look back I find that I
even have an ospm_system module any more. But the system still powers
correctly. The last message I see on the screen now is "calling
acpi_power_off". This isn't a module; it seems to be a function that's
built into the kernel when ACPI support is enabled.
