Description Adam Williamson 2010-10-08 15:20:03 EDT
Filing this for easy downstream tracking of this issue. The touchpad on 2010 model Sony Vaio Zs is known not to be working without the use of the 'i8042.nopnp=1' parameter. Even with this parameter, on about 1/10 boots, both the touchpad and the internal keyboard fail to work.

An upstream patch is available for this:


and has been accepted into acpi-test this week:


so it should be OK to take this into Fedora kernels (recommend F13/F14/F15). I've been running with this patch on my Z for a while and it has not caused any regression; touchpad works on boot and I never see the intermittent failure of both touchpad and keyboard at boot any more. Every so often they fail to work after a resume from suspend, but that is also the case without the patch, so the patch doesn't make anything worse.
Comment 1 Adam Williamson 2010-10-08 15:20:39 EDT
proposing as NTH.
Comment 2 Adam Williamson 2010-10-15 13:12:37 EDT
Reviewed at the 2010-10-15 review meeting. We accepted this as NTH if the kernel team wants to add it to an update necessary for blocker bugs; we don't want to see a kernel build just for this bug.
