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!! (that one I can kill without losing any major functionality)

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.

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!
(just had another key stick but again, nothing in the logs)
