Changing to 1 or 2 > minutes might help. All in all I have three apps that poll.. I've slowed them down a little and it still seems to co-incide with me typing or using the touchpad (Murphy is a swine like that). One polls once per minute, one polls every 30 seconds and one polls every 2 seconds!!

I've used ec_intr=0 now and it has appeared to increase the reliability somewhat.. Just got my 1st set in dmesg while composing this e-mail, however I did not notice the mouse lockup or any keys stick. I did have a key stick about 15 mins ago, but it left no messages in the logs. psmouse.c: TouchPad at isa0060/serio4/input0 lost sync at byte 1 psmouse.c: issuing reconnect request Have not figured out how to disable the ACPI ec yet, but I'll get my head in that code tonight and have a look around. All in all it looks like a definite improvement. I'll keep playing. Many thanks!
