I just ran the tests you requested with some extra steps which I hope won't confuse things. Here's the sequence I followed: - Enabled i8042 debug - sudo rmmod psmouse. Touchpad of course becomes unresponsive. - sudo pm-suspend - Wake the machine by pressing power - At this point touchpad is unresponsive. - Collected dmesg-1.txt - sudo pm-suspend - wake the machine by pressing power - At this point touchpad is still unresponsive. - Collected dmesg-2.txt - sudo modprobe psmouse. Touchpad begins responding. - Collected dmesg-3.txt - sudo pm-suspend - wake the machine by pressing power - At this point touchpad is again unresponsive. - Collected dmesg-4.txt To avoid attaching largish files to this email, I put the logs on a publically-accessible http server at: http://people.canonical.com/~roadmr/lp715267/. Please let me know if you prefer something else. Thanks in advance for your help! - Daniel Manrique -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
