I am now using kernel gentoo-sources-2.6.3-r2 with xfree-4.3.0-r5. When I start the computer, my Synaptics touchpad is recognized by the kernel, and works fine in XFree86. However, when I suspend, once I resume the computer, neither the touchpad nor the buttons work. I can restart xfree but the buttons still don't work until I reboot, making me think this may be a kernel issue. I am using APM instead of ACPI since my hardware doesn't seem to want to cooperate with ACPI very well right now. Reproducible: Always Steps to Reproduce: 1. Boot system using APM (i.e. acpi=off on command line). Start xfree (or gpm). 2. Move finger across touchpad. The mouse cursor moves. 3. Suspend the computer. 4. Resume the computer. Actual Results: The mouse cursor does not move and the buttons do not respond on the touchpad. Expected Results: The touchpad should behave normally after the computer resumes.

are you suspending to disk with swsup? (software suspend) if so that has quite a few known issues, and unfortunately, it will most likely be related to that
Not suspending to disk. I'm using "apm --suspend" to suspend. I just installed gentoo-dev-sources-2.6.4-r1 and get identical results - upon resume, the touchpad is still completely unresponsive until "/sbin/reboot".
this is quite likely an upstream bug but I shall ghunt into the code tonight to try and find the reason why.
upstream are aware of this issue. Once a solution has been made I shall include it within the patchset until it hits mainstream.. many thanks for taking your time to log this.

A similar thing happens to me on 2.6.14-gentoo-r5 (AMD64) using ACPI and swsuspend. Only that with me the buttons work ok, and the tap on the touchpad itself works as a first button click only on links, buttons etc, but not for starting a selection of e.g. a text or icons in the file manager or desktop. Could this be caused by the same problem or should I open a new bug report?
