Hello,

with -rc2 (-rc1 didn't show this behaviour) I get the following when
modprobing psmouse.ko:

atkbd.c: Spurious ACK on isa0060/serio0. Some program, like XFree86,
might be trying access hardware directly.

and the touchpad is not detected at all.

The ps2_adjust_timeout function seems to be the cause, restoring the old
fixed timeout in ps2_command seems to cure this issue (see diff below).
It could be probably done better by detecting which command misses the
the last bytes and recalibrating ps2_adjust_timeout instead. Or maybe
checking the return value of wait_event_timeout for a next round of
wait?

This is the device (on a Vaio GR), which other info could I provide to
better diagnose the problem?

Could you please do "echo 1 > /sys/modules/i8042/parameters/debug";
reload psmouse module and send me dmesg please?

Thanks!

oh, it seems I'm not able to reproduce the error anymore!
I need some rest now, I'll try again tomorrow morning (I must be missing
something stupid right now) and report to you again.

Thanks

Could be the enabled debug is adding extra delay, making the problem
impossible to reproduce. IIRC, we've seen this with an ALPS pad, too,
Dmitry, right?

It was just a tad different - on one of the boxes alps-resume-typo
patch worked only with debug. 2 other boxes worked just fine without
debug.

I just can't see what could be wrong with ps2_adjust_timeout()...
It only reduces timeout to 100 ms when doing reset, exactly like
the old code did. Vojtech, can you see anything there?

No, I don't. I'll keep looking, though.

Sorry, it took me a while but I got the error finally (see below for the
debug log). Anyway I suspect it's most likely a bios or hw problem, a
cold boot shows the issue, simply reboot-ing cures it (keeping the
ps2_adjust_timeout in place).
Also, not every cold boot shows the issue, I reproduced it at the 3rd
try today.
So I believe all my previous suspecions are mostly void.

Here's the log:

Does it show this line when touchpad is being detected? 
Do you have PNPACPI turned on?

Revision 5.3 is suspicious. The last posted one is 1.1
Again, when touchpad is detected, does it show this or 1.{0|1}?

We are trying to talk to AUX port but KBC replies as if data
is coming from the keyboard port.

Does it help if you boot with "usb-handoff" kernel option? Another
one would be "i8042.nomux". Btw, does your laptop have external
PS/2 ports?

yes

# CONFIG_PNPACPI is not set

nothing at all, no multiplexing controller and most important only 2
ports

PNP: No PS/2 controller found. Probing ports directly.

Well it's pretty hard to say currently I've only been able to trigger
this problem only twice in at least 6 cold boots.
Will try later anyway :)

As said, I remember having this problem in the past, here's the thread:
http://marc.theaimsgroup.com/?l=linux-kernel&m=108211185919825&w=2
it seems we already talked about it!

Ok, it seems I can now reliably reproduce the wrong detection (by
removing the power supply before a cold boot) and 'usb-handoff'
definitely helps.

Oh, and I don't have any extra ps/2 port available.

Since we (SUSE, many thanks to Andi Kleen and Andrea Arcangeli) have
already fixed most of the breakage "usb-handoff" causes on certain
(nvidia, etc) boxes, because of unusual memory layouts and iounmap()
that can't cope with that, I believe it'd be a good idea to enable
"usb-handoff" on vanilla kernels by default as well - SUSE already has
it enabled for more than a year.
