After many many tests (latest with 8.04 / kernel 2.6.24-12-generic) I'm still unable to find an event making the system go into this state. Sometimes it occurs after a few minutes, and sometimes not for hours. Obviously this is very strange.
Blacklisting yenta_socket doesn't fix the problem. But one thing is for sure, when it occurs, modprobing yenta_socket reset the wakeups rate to a standard value. This bug is a showstopper for laptop users as this event drains 400mA (as a comparison backlight at full power pumps 500mA on DELL D630) I'll continue this discussion on the power ML and let you know if there is any progress. BTW, in attachment, a small script to monitor wakeups and battery life.
