I just realised that in my haste I tested it against the 2.6.11.6
kernel, not the 2.6.12rc{1,2} as you instructed. I'll retest as soon as
I can.

No, just nomux. We are still battling whether we shoudl have usb-handoff on

Not sure, sorry.

Input: automatically disable MUX mode on Toshiba Satellite P10
because it interferes with ALPS touchpad detection and
causes horrible death on reboot. Since P10 does not have
external PS/2 ports MUX mode does not have any advantages
over legacy mode anyway.

Have you tried compiling i8042, atkbd and psmouse as modules and adjusting the init scripts so they are all loaded after USB drivers are loaded - does it also cause lock up on reboot?

i8042 controller on Toshiba Satellite P10 notebook - patch
Hello all
A while back there was quite a discussion on this issue and then
specifically "i8042 timing issues". I refer you to
http://lkml.org/lkml/2005/1/27/11 for more detail.
It turns out that it was the case that the i8042 controller responds too
late on commands, for example, we issue a AUX_LOOP command, whilst
waiting for the response it would time out, however, when issuing
AUX_TEST we will get the response for AUX_LOOP. It turns out this is
also true for the MUX and KBD parts of the driver. The attached patch
resolves this issue by providing a configurable option to issue commands
that expects results twice (not sure whether this is a good idea - but
it seems all commands either set some value or query some value).
Between the two commands it calls i8042_flush() to make sure that there
are not any earlier responses in the buffer.
I've built the patch against linux-2.6.11.6 and it should apply cleanly
(I've attached the patch cause it is about 80 lines in length and I fear
mozilla will break the formatting).
The patch fixes the problem for me - not sure how many other people out
there has the same issue. It provides a configurable option which can
be selected in the kernel configuration to actually enable this (albeit
enabling it should only result in a minor performance hit should it be
enabled needlessly - I think). Should the option not be enabled the
code remains 100% unchanged (except for one extra level of indentation).
I'm not sure what the policy regarding #ifdefs are, especially
considering they enclose the endpoints of a loop, please review and comment.

With my patch I do get the ALPS support though - something which I didn't get with usb-handoff, nor with acpi=off, nor with simply hacking out the AUX_LOOP and AUX_TEST tests and just assuming the hardware is there (I saw ALPS yesterday for the first time in my life for that matter). OT: I think I prefer synaptics multi-finger tapping to the tapping in specific locations to get right and middle clicking, but that is another story that probably has nothing to do with the kernel, and quite likely something that is configurable in the synaptics xorg driver.

This sucks (don't get me wrong - I appreciate that my hardware is now functioning properly - only things afaik that doesn't work now is the SD card reader and suspend/hibernate and with ati-drivers there is not a chance in hell that that'll ever work, neither of which is of critical importance for me). Yes, with 4 ports your external mouse is independent from the touhpad. When you have only 1 port you can't use touchpad's extended mode together with an external mouse. No external PS/2 port :). A-haa.. Well, in that case we'll cheat ;) and just disable MUX mode for your Toshiba via a DMI quirk, like we do for certain Fujitsus. If there is no external port there is no reason to have the controller in MUX mode. Could you please send me output of 'dmidecode' utility? -- Dmitry - To unsubscribe from this list: send the line unsubscribe linux-kernel in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Ok, great! Please try the patch below (against 2.6.12-rc{1|2}).
Would this quirk also imply usb-handoff?
No, just nomux. We are still battling whether we shoudl have usb-handoff on
by default.
One (hopefully) last query, lspci reports the following device (which I
assume is the SD card reader):
:02:04.2 Class 0805: ENE Technology Inc: Unknown device 0550
How can one confirm what this is?
Not sure, sorry.

Input: automatically disable MUX mode on Toshiba Satellite P10
because it interferes with ALPS touchpad detection and
causes horrible death on reboot. Since P10 does not have
external PS/2 ports MUX mode does not have any advantages
over legacy mode anyway.
