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: http://marc.info/?l=linux-acpi&m=127570466420246&w=2 and has been accepted into acpi-test this week: http://marc.info/?l=linux-acpi&m=128591337505051&w=2 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.
proposing as NTH.
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. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
kernel-2.6.35.6-45.fc14 has been submitted as an update for Fedora 14. https://admin.fedoraproject.org/updates/kernel-2.6.35.6-45.fc14
kernel-2.6.35.6-45.fc14 has been pushed to the Fedora 14 stable repository. If problems still persist, please make note of it in this bug report.
This is fixed, as per the above note (don't know why it didn't result in the bug being closed). yay! -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
