2.6.0-test1, -test4 control key "stuck"

[xsdg <xsdg@freenode.org>]

[-- Attachment #1.1: Type: text/plain, Size: 11231 bytes --]

Hi.  I recently got a new Toshiba M15-S405 laptop, on which I installed Debian SID (using the Sarge netinst bootcd).  I installed the debian 2.6.0-test1 kernel and booted into it.  I noticed that often, pressing keys under this kernel would result in messages such as [1] printed to the console.

The Problem Now:
	My current problem is that once in a while, a control key will become "stuck", as interpreted by all applications.  By "stuck," I mean that pressing and releasing the control key will not cause it to become "unstuck."  All keypresses, whether in X or on a VT, are interpreted as if the control key were being pressed.  The only way I have found to unstick the key is by pressing random keys in rapid succession (sometimes holding the control key, and sometimes just making sure I press it a few times during the key-pressing frenzy).  I believe that this problem is related to the messages ([1]) printed to kern.log and the console.  This problem has occurred under 2.6.0-test4*, and may have occurred under 2.6.0-test5-mm1 (I don't remember).

	As I spend most of my time in x-windows, this problem has only occurred while I was using x-windows; I am not sure whether it would or would not occur while in the console or while x-windows is not running at all.  This problem has occurred both while using NVidia's proprietary driver and while using the open-source driver provided with xfree86 4.2.1

	Most recently, this problem manifested itself by (as far as I can tell) switching the keyboard keymap (this, occurred while I was in X, with Mozilla on the current workspace).  After switching to vt2, I am now unable to return to X (vt 7).  Pressing the numeral keys acts as if shift were held down while using an odd alternate keymap (2 -> "^U", 4->"$", [7-0] -> ["{", "[", "]", "}", "\"], e -> Euro symbol).  You can find the physical layout of my keyboard at [2].  While pressing the shift key, no characters are displayed on the console.  Pressing <alt>+Fn or <ctrl>+<alt>+Fn to switch to another VT does not do anything; the same occurs when trying <alt>+left/right


Kernel Version History:
	After installing most of the necessary tools, I compiled a vanilla 2.5.73 which eliminated the problem shown in [1].  A little later, I compiled and booted into 2.6.0-test3, and then dropped back to test1-ac3 (because cardbus/pcmcia hard-locked during boot).  -test1-ac3 did not exhibit the problem.  I moved to -test4 when it was released, which exhibited the problem.  Because swsusp was broken in -test4 (on my system, at least), I dropped back to 2.6.0-test1-ac3 after a few days.  Later, I upgraded to -test4-mm4, -mm6, and -test5-mm1, all of which exhibited the problem.  After running -test5-mm1 for about a day, I dropped back to -test4-mm6 (I don't quite remember why).
