Comment 2 for bug 2006458

Hi Mario,

This is exactly what I was thinking of when reviewing the timing of
wakeup events occurring on my system. My first assumption was like
this:
1. system fw check battery actual charging level, target charging
level and charging rate
2. system fw compute compute estimated arrival at target charging level
3. sleep until arrival at charging level
4. wake up
5. goto 1

Such an approach will eventually converge to "oszillate" around target
charging level which can be proved by the systems wake up logs.

Anyway, I still don't get why upgrading the wifi-cards firmware to a
more recent version fixes the problem.

Would you mind to elaborate on this a bit more?

Thanks,
Carsten
