After linux-3.2.1 update, module has disappeared?

[sparklespdx]

After kernel update, acpi_call module fails to load. Modprobe reports that it doesn't exist. I downgraded to the most recent kernel version I had working; same issue. I have done a full re-clone, no effect.

Same problem, but with kernel 3.9.6-200.fc18.x86_64 :

[marco@Marco-HP acpi_call]$ sudo make
make -C /lib/modules/3.9.6-200.fc18.x86_64/build M=/usr/local/bin/acpi_call modules
make[1]: Entering directory `/usr/src/kernels/3.9.6-200.fc18.x86_64'
  Building modules, stage 2.
  MODPOST 1 modules
make[1]: Leaving directory `/usr/src/kernels/3.9.6-200.fc18.x86_64'
[marco@Marco-HP acpi_call]$ insmod acpi_call.ko
[marco@Marco-HP acpi_call]$ modprobe acpi_call
modprobe: FATAL: Module acpi_call not found.
[marco@Marco-HP acpi_call]$ sudo bash 
[root@Marco-HP acpi_call]# echo "\_SB.PCI0.PEG0.PEGP._OFF" > /proc/acpi/call
[root@Marco-HP acpi_call]# cat /proc/acpi/call
0x0[root@Marco-HP acpi_call]#

This call succeeds, but after a reboot /proc/acpi/call no longer exists.

Any ideas?

You have to use insmod since modprobe searches elsewhere for the module.

If you want to use the module on every boot you'll need to add insmod /path/to/the/module.ko to the init scripts somewhere, /etc/rc.local might work depending on your distro.
