Description of problem:
With kernel-2.6.12-1.1372_FC3, toshiba_acpi is working, but after upgrade to
rnel-2.6.12-1.1376_FC3 and reboot, it fails to load, saying No such device.
FnFXd, a daemon for managing the Fn key, used for brightness control, sleeping
and so on doesn't work either, since it requires toshiba_acpi to be loaded.
When I boot the previous version, kernel-2.6.12-1.1372_FC3, the module works and
so does FnFXd.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Grab a recent Toshiba laptop (with Toshiba BIOS)
2. Install kernel-2.6.12-1.1376_FC3,
3. when using FnFX, an error message will be printed as soon as it starts,
otherwise search for /proc/acpi/toshiba - should be loaded out of thebox, or
try modprobe toshiba_acpi
Actual Results: toshiba_acpi isn't loaded, saying No such device
Expected Results: toshiba_acpi just works with a Toshiba laptop, as did previously

I've cloned this bug for FC4, which has the same problem with

linux-2.6-acpi-rollup-20050902.patch is included), and the same problem exists.
Kernel bug 4953 appears to address this:
There is a patch (for 2.6.13-rc6), as well as a workaround (adding kernel
Confirming, kernel parameter acpi_specific_hotkey added to kernel
(2.6.12-1.1376_FC3) command line solves the problem for the time being.
fixed in cvs. will be in next update.
From User-Agent: XML-RPC
kernel-2.6.12-1.1380_FC3 has been pushed for FC3, which should resolve this issue. If these problems are still present in this version, then please make note of it in this bug report.
Confirming fix, thanks. acpi_specific_hotkey is no longer needed.
