Hi Jonathan,

For starters, did you see this in dmesg? :

[    0.422648] i8042: PNP: PS/2 Controller [PNP0303:KBC0] at
0x60,0x64 irq 1
[    0.422652] i8042: PNP: PS/2 appears to have AUX port disabled, if
this is incorrect please boot with i8042.nopnp

And did you try booting with "i8042.nopnp" ?

Also what is the output of:

ls -l /sys/bus/i2c/devices

and of:

ls -l /sys/bus/acpi/devices/ELAN066C:00/

and of:

cat /sys/bus/acpi/devices/ELAN066C:00/status

?

Hey Hans,

Yeah, I did see that in my dmesg and did try i8042.nopnp by itself and
with combinations of pci=nocrs and the other i8042 options, with no
effect except breaking audio.

The above is exactly the same on a clean Fedora 6.5.6 kernel and my
custom build with the alias added to elan_i2c.

Thanks for the swift reply!
