Mouse/Keyboard hangs..

Mouse/Keyboard hangs..

[John Clemens]

Hi all..

I'm having an issue with my laptop.. the same issue i've had for since I
baught it..  Under linux the mouse (synaptics touchpad) and/or keyboard
will suddenly lock.  All input stops.  I can telnet in and shutdown
cleanly, but that doesn't help recover that I've got on my screen in X (or
the console).

Hardware: HP n5430 laptop, synaptics touchpad, trident XP graphics,
standard low-end laptop.

Here's the really odd part.  When it happens, if i notice quickly enough
and hit the power switch on my laptop for just a split second (not the 5
seconds to power off).. it sometimes comes back!  It's happened twice
while typing this email in pine using a text console (no X, no mouse).
But if I wait too long (a few seconds)...no matter how many times i nudge
the power switch, it never comes back.  Sometimes it's more frequent then
others.. sometimes I'll go for days/weeks without seeing it.

I've been seeing this since I got the laptop, and I've run almost every
2.4.x (x > ~10) and a lot of 2.5 kernels on here (currently, 2.5.54).
The behavior is a little different recently though with the 2.5 series.
Now, sometimes when it comes back, i get the character i was typing
repeated (as if a key was stuck) until i hit another key.  This change
could be related to the new i8042 changes in 2.5, I'm not sure.

I've tried : APIC, no APIC.
	     ACPI, no ACPI.
	     ALI IRQ router, ACPI IRQ router.
	     psmouse_noext command line arg.
	     powernow-ing the CPU down to 500Mhz (850Mhz duron... heat
							related?)

All to no avial.  The only possible reason I can think of that hitting the
power button could help is that triggers ACPI, which uses IRQ 9...
and I seem to remember something about IRQ 2 (cascade) and IRQ 9 (ACPI)
being one in the same, really.. maybe we missed an interrupt somewhere and
hitting the power switch forces IRQ 2 to trigger, somehow triggering IRQ
1 (keyboard) as well?  It's a stretch and my understanding of PC IRQ
logic is sketchy at best.

Does anyone have any ideas?

/proc/interrupts and relevant dmesg output is below the sig..
thanks,
john.c

Hi,

did you also try to disable apm (so disable acpi and apm) ?

On my thinpad R31 a loop reading of /proc/apm makes mouses and keyboard usage 
almost impossible (it is said that its the fault of the BIOS), perhaps your 
problem is related.

Re: Mouse/Keyboard hangs..

[John Clemens]

Hi Bernd,

Unfortunately, yes, I've tried without APM too.  also, I don't have any
programs running that query apm or acpi.  Thanks for the suggestion
though.. any others?

Strange.. I have something very similar on hp omnibook xe3 here,
except that:

1) I do not think it responds to the net when hung

2) it *allways* recovers after power button

3) it seems to only happen in 2.5.X here, maybe it has something to do
with ACPI?

Mine remembers up to few keystrokes I was typing...

The XE3 is approximately the same model.  Is yours AMD or Intel based? I
seem to remember there was even an AMD-based "omnibook xe3" that was the
exact same laptop rebranded...  but there were also P3 ones.  To give you
an idea of how close they were, I flashed my bios with (appearently) the
wrong bios, and my machine thought it was an omnibook xe3 for a long time
;) (until it went if for service and they flashed it back)

full specs for mine: http://www.deateer.net/john/PavilionN5430.html

> 1) I do not think it responds to the net when hung

I haven't tried in a loooooong time.  I'll have to try if/when it happens
again.  It's just easier to big-red-switch it, since ext2 and ext3 are soo
good about powerdowns :)

I'd say mine does about 80% of the time.

I've seen it in both 2.4 and 2.5.. but it seems to happen more frequently
in 2.5.  I've tried to booting with "acpi=off, pci=noacpi" and it still
happens :(.. Or were you suggesting it has something to do with the
hardware/firmware that implements ACPI?

FWIW, on the HP user support forums for pavilions, people were
complaining about "mouse locking up" under windows...and those were cured
with an updated synaptics driver.  however, they never mentioned a
keyboard lock, and I -know- I've seen errors when nothing's even touching
the mouse.. ie, on the console, without GPM running.

Mine does too..but repeats the last one occasionally.

Actually, it *probably* also happened in 2.4 with apm, but it always
recovered automagically within second or so -- so it was "damn that
machine is unresponsive" not "keyboard failed again, time for power
button".

Same here. But I also see it happening while *only* using mouse.

Yes, it can buffer only so-many keys and if the last one it *can*
remember is press, you get an autorepeat.
