Description Radek Bíba 2005-08-31 13:17:48 EDT

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.10) Gecko/20050720 Fedora/1.0.6-1.1.fc3 Firefox/1.0.6

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):
kernel-2.6.12-1.1376_FC3

How reproducible:
Always

Steps to Reproduce:
1. Grab a recent Toshiba laptop (with Toshiba BIOS)
2. Install kernel-2.6.12-1.1376_FC3,
3. Reboot
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
kernel-2.6.12-1.1447_FC4, Bug #167281

Comment 3 Mace Moneta 2005-09-15 19:13:28 EDT

I checked kernel-2.6.12-1.1378_FC3 (since CVS noted the
linux-2.6-acpi-rollup-20050902.patch is included), and the same problem exists.

Comment 4 Mace Moneta 2005-09-15 20:29:22 EDT

Kernel bug 4953 appears to address this:

http://bugzilla.kernel.org/show_bug.cgi?id=4953

There is a patch (for 2.6.13-rc6), as well as a workaround (adding kernel
parameter acpi_specific_hotkey).

Comment 5 Radek Bíba 2005-09-19 03:05:03 EDT

Confirming, kernel parameter acpi_specific_hotkey added to kernel
(2.6.12-1.1376_FC3) command line solves the problem for the time being.
Thanks Mace!

Comment 6 Dave Jones 2005-09-23 21:53:25 EDT

fixed in cvs. will be in next update.

Comment 7 Fedora Update System 2005-10-20 10:30:07 EDT

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.

Comment 8 Radek Bíba 2005-10-20 12:55:26 EDT

Confirming fix, thanks. acpi_specific_hotkey is no longer needed.
