Re: Suspend removes /sys files needed for touchpad

Hi.

Same problem here. My /sys/class/input/input2 entry disappears after
resuming.
I noticed these lines in dmesg output after resuming:

.....
pnp: Res cnt 3
pnp: res cnt 3
pnp: Encode io
pnp: Encode io
pnp: Encode irq
pnp: Failed to activate device 00:03.
pnp: Res cnt 1
pnp: res cnt 1
pnp: Encode irq
pnp: Failed to activate device 00:04.
.....

I see there are similar errors in your output. I try to run lspnp after
resume to see whitch the devices 00:03 and 00:04 are. Result:

lspnp: /proc/bus/pnp not available

This directory is missing. (At the moment I can not tell if it existed
before...)
