To provide the sequence of what I think is relevant log files, I did this: boot cold in to 3.2.0-17 -- trackpad not working (precise-kernel-coldboot) warm reboot into 3.2.0-17 again -- trackpad not working (precise-kernel-reboot) warm reboot into 3.2.1-030201 -- trackpad works (upstream-kernel-reboot) warm reboot into 3.2.0-17 -- trackpad works (precise-kernel-afterupstream)
I saved Xorg.0.log and dmesg after each boot. After stripping off the timestamps, I notice that the main difference is that the apple trackpad is initialized *much* later with the 'afterupstream'. Also I notice that this message is no longer in dmesg after the upstream 3.2.1 kernel is booted: bdi 1:0: hash matches acpi device:19: hash matches I have attached the results of this debugging sequence, the tags in parenthesis above correspond to the log file names. ** Attachment added: "debug-trackpad.tgz" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/936552/+attachment/2759760/+files/debug-trackpad.tgz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/936552 Title: MacBookAir 4,1 trackpad does not work with synaptics driver until boot into 3.2.1 kernel..
