Comment 729 for bug 752542

Attached is result of get-acpi-info.sh
Kubuntu 14.04, the problem is 10-15 second freezes in Kde eg. can click on an icon then can't do anything for 10-15 secs then the program runs, can have a month or so when everything is fine then after an update back to the above problem. Currently it's the worst it's ever been after an update installing kernel 3.13.0-35 On startup i have a script that dumps the output of dmesg to a file named by date and time could upload one from a previous state when all was working, have noticed odd things re ACPI in syslog eg.
