Toshiba keyboard lockups

Toshiba keyboard lockups

[Fernando Paredes]

There was a previous thread on this, last month.

I updated to 2.6.6 and I still get these random lockups. Nothing in 
dmesg or /var/log/messages. Too annoying as I have to reboot the machine 
constantly. Does anyone know the status on this? Is t a toshiba hardware 
bug (is that possible?) or a bug in serio.c or keybd.c?

Thanks!

It's most probably Toshiba-related, because it does not happen on other 
hardware, it seems.

I've got a simple patch from Grzegorz Kulewski to help trace the problem, but 
I haven't got a lockup since.  The patch is as follows:

Please try to apply it and you should get something in the logs when a lockup 
occurs (ie. kernel warning + call trace).

In case anyone's interested...

Applied these patches. Nothing while tail'ing /var/log/messages. Nothing 
in the root console that I can see either.

Patched the source to 2.6.6. Still get the same lockups, totally random.

Any more ideas?

Not sure if I have exact problem like you do, but at least I have something
similar. Once in a while keyboard suddenly stopps working, touchpad still work
though (I have Toshiba Satellite Pro (centrino based) laptop here).
I figured out that if I leave the keyboard for some time (up to 2 minutes),
it starts to work again, at least this was the case with XFree 4.4,
during those no-keyboard times, mouse cursor was moving with small jumps
(when keyboard works it moves smoothly).
I upgraded to FC2 (and hence to xorg X server) today, and lockup happened
once already, the "wait for some time" strategy did not work, so I
remembered initially I thought this was something bad pressed on keyboard
(btw, usually lockups happens when I press several keys at the same time by
accident (but not always when I do this)), so I was pressing various 
modifier keys and Fn-Fx stuff. (Fn is one key, Fx is set of functional keys).
So today after some waiting I jut pressed alt+ctrl+shifts in some
conbinations and it unfroze almost immediately to my surprise.
Also I can add that sometimes when I press more than one alphanumeric key,
I get this sort of message from kernel:
"atkbd.c: Keyboard on isa0060/serio0 reports too many keys pressed."
Also sometimes (not always) after the freeze/unfreeze I get various messages
from atkbd.c, here are some examples:
atkbd.c: Unknown key released (translated set 2, code 0x7a on isa0060/serio0).
atkbd.c: This is an XFree86 bug. It shouldn't access hardware directly.
(numbers may differ from time to time)
atkbd.c: Unknown key pressed (translated set 0, code 0x1d on isa0060/serio0).
atkbd.c: Use 'setkeycodes 1d <keycode>' to make it known.
(numbers may differ from time to time voth in keycode and in translated set)
atkbd.c: Unknown key pressed (translated set 0, code 0x22 on isa0060/serio0).
(again numbers may vary)

atkbd.c: Failed to enable keyboard on isa0060/serio0
(this is some ancient message from October 25th, 2004, seen it only once,
just prior to reeboot, according to logs, do not remember details).

And also I often see multiple
"input: AT Translated Set 2 keyboard on isa0060/serio0" messages.
And new ones are appearing after the freeze/unfreeze. (not every time, though).

May be that will help someone.

Bye,
    Oleg

I have had similar issues with a toshiba laptop keyboard with 2.6+ kernels
for awhile. I have found that repeating the last key combination pressed
will "unlock" it. No logs or dmesg entries are produced when the lockup
occurs.

Its a Toshiba Satellite 1410-S173, currently running 2.6.7-rc2-mm2

Re: Toshiba keyboard lockups

[Fernando Paredes]

To the benefit of developers, here are the tracebacks for today. I 
haven't experienced any lockups so far, BUT i have experienced two weird 
experiences:
1) The space key seemed to get stuck and it unstock by pressing <backspace>
2) The 'n' key stuck and unstuck itself, displaying about 5 'n' on my 
screen.

For both events I have an identified backtrace from 'dmesg' (thanks, to 
the traceback code in atkbd.c). There is another event there in the logs 
where I didn't notice in the keyboard.

As someone in this thread expressed earlier, it seems that the driver is 
requesting a keyboard reconnect. This shouldn't be hapenning, right?

Here are the traces with their desrcibing title:

I know that "me toos" are of limited use, but I have also been 
experiencing this problem. I can give some specific details, and on 
request am willing to work to produce additional diagnostics / test 
patches etc.

I am using a Toshiba Satellite 2410-603 with a P4 M processor, and I 
have experienced difficulties with Gentoo-patched 2.6.3 sources, 
Gentoo-patched 2.6.5 sources and vanilla 2.6.6 sources, with 
CONFIG_PREEMPT both on and off.

Of the three, 2.6.3 seems the least affected - although I do get 
occasional keyboard lockups, if I use the mouse for a few seconds the 
keyboard becomes re-enabled. On both the 2.6.5 and 2.6.6 kernels a 
keyboard lockup seems permanent, although I haven't tried leaving it for 
more than a minute or two.

I too can see warnings from atkbd.c in the kernel messages (on all three 
kernel versions) reporting 'Unknown key pressed' and 'too many keys 
pressed'.

I am well aware that Toshiba keyboards are buggy - under 2.4 kernels I 
experienced multiple key event problems, so I think what's being asked 
here on this thread is not that the keyboard driver be "fixed" as such, 
but that, if possible, it is extended to work around the buggy hardware.

Thanks,

Sean

Re: Toshiba keyboard lockups

[Gabriel Lavoie]

I just reinstalled Gentoo this week and the problem appeared! With 
kernel 2.6.5- I didn't had this problem. I now have it with 2.6.6 and 
2.6.7. I'm using a Toshiba Satellite A20 (Canadian version).

If you could track down which change between 2.6.5 and 2.6.6 makes the
difference for you, that'd be very helpful.

I've been having such problems since approx. 2.6.5-rc2 (anyway, the release in 
which the Prism54 driver appeared for the first time ;-)) on a Satellite 
1400-103.  However, I've found recently that it's sufficient to press the 
left SHIFT after a lockup to "release" the keyboard.  There may be some other 
specific key or a combination of keys that helps on other Toshiba models, I 
guess.

Yours,
