Subject: 2.6.11-rc4: touch pad misidentified (ALPS instead of ImPS/2)

Hi,

the new 2.6.11-rc series has another problem for me, my touchpad (Toshiba
Laptop) stopped working. I guess this has to do with "[PATCH] ALPS touchpad
detection fix" that was posted about 4 weeks ago. The kernel says while
booting:

newton kernel: mice: PS/2 mouse device common for all mice
newton kernel: input: AT Translated Set 2 keyboard on isa0060/serio0
newton kernel: ALPS Touchpad (Glidepoint) detected
newton kernel: Disabling hardware tapping
newton kernel: input: AlpsPS/2 ALPS TouchPad on isa0060/serio1

and when I try to use it, the following is spit out:

last message repeated 2 times
kernel: psmouse.c: TouchPad at isa0060/serio1/input0 - driver resynched.
kernel: psmouse.c: TouchPad at isa0060/serio1/input0 lost sync at byte 1
last message repeated 2 times
kernel: psmouse.c: TouchPad at isa0060/serio1/input0 - driver resynched.
kernel: psmouse.c: TouchPad at isa0060/serio1/input0 lost sync at byte 1

This goes on until I stop touching the touchpad. With up to 2.6.10 there were
no problems and the kernel said:

newton kernel: mice: PS/2 mouse device common for all mice
newton kernel: input: AT Translated Set 2 keyboard on isa0060/serio0
newton kernel: input: ImPS/2 Generic Wheel Mouse on isa0060/serio1

I haven't compiled in any ISA support, but I don't think this can be the
reason since I haven't changed the kernel config between 2.6.10 and 2.6.11.

Thanks for any help,
Michael

Hi,

Could you please boot with "i8042.debug log_buf_len=131072" boot
option, work touchpad a bit and send me your full dmesg (or
/var/log/messages), please?

I the meantime to get your touchpad working (after you send me the
dmesg) add "psmouse.proto=exps" to your boot options (or add "options
psmouse proto=exps" if psmouse is compiled as a module).
