I'm using acpi_call on a Fedora 20 too switch off my graphic card:
01:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Mars [Radeon HD 8730M](rev ff)
My laptop is a Samsung 7 ultra.

Using the 3.11 kernel acpi_call works fine, but as soon as I switch to a 3.12.x kernel the system become unusable after a few seconds after starting X.
I've compiled acpi_call with the debug prints, but the logs show it terminates correctly. However, a few seconds after switching off the radeon card, the system become very slow (it appear to be frozen).
The errors in the log file are the following:

The system continues to repeat the last two lines and does not respond to any other input
I had similar symptoms with ubuntu 13.10, but I did not check the log, hence I cannot confirm that it is due to the same issue.

It seems that it is possible to avoid the issue if the radeon module is not loaded. I suggest to blacklist radeon before using acpi_call.

tested on fedora 20 with kernel versions 3.12 and 3.13
