#1597: after a long suspend time, kernel thread events/0 sits eating 30% cpu

Comment(by Matthias):
I did a lot of tests with monitor-scripts to catch the situation and can
confirm:
- the runaway (consuming CPU) of events/0 occurs also without using
suspend;
- it occurs without using GPRS, GPS and Wifi, just acting the FR as a GSM
phone
- it occurs exactly after 18h+16...17min uptime (which is in seconds a bit
more
than the unsigned short value of 65536)

Comment(by andy):
As it says above the issue can't be reproduced (allegedly) on 2.6.28
kernels, we won't be backporting the change that we think solved it to
2.6.24.
