But no physical I/O which should offset that. I've been running mine with ramzswap for many months and haven't noticed any reduction in battery life. I don't have any useful data or observations for the "turbo" kernel yet.

well there is the swap_prefetch to consider now, not sure how that affects things.

Hm, the plot thickens. It turns out my swap notify patch is identical to 08-patch_swap_notifier_generic_2.6.25.diff, but the DT kernel doesn't exhibit my problem. I must be screwing up somewhere else...

Doesn't, at all. It is a veeeeeery loooooooong period timer.

Are you using my ramzswap 0.5.5 modules? The 0.5.4 release from compcache homepage is buggy and crashes on swapon/swapoff. Ah, and don't expect the 0.5.3 modules from ramzez-init to be compatible, either.

With your kernel, yes. Previously I was playing with hand-rolled 0.5.4 ones on CSSU + swap notify kernel.

Aha, that seems to explain it then. But... where did you find 0.5.5?! It's not listed in http://code.google.com/p/compcache/downloads/list at least.

Edit: I see, you didn't "find" it, you fixed it yourself - thanks! :-)

I was too busy to investigate battery problem but today I lost 20% of charge as I listened music for an hour. (quasar using mplayer).
May be it is because of Advanced sistemui made by auouymous, but I think it is Diablo turbo.

Kroll, that battery usage is consistent with the use of mplayer to play music, no matter the kernel. If you use mplayer to play music the cpu will be running at 400 MHZ constantly, since the cpu is doing the decoding, and that means 5 hours of battery life. 1h/5h=20%
I'll address any issue you find, but you have to make a proper test, reproductible, and with both kernels to spot the difference. Please, understand that I can't test everything myself, just don't have enough time.

Are you using 400/133 or 333/220 ratio? Try running `/etc/init.d/advanced-systemui stop` as root before you listen to music next time and see if the battery still drops by 20% in an hour.

Listening for disable_ts and turning off polling while locked would be a good start. How hard would it be to use a dynamic polling rate that decays between two tunable values the longer no data is available?

What does op_active do?

Usually i listen music for 2-3 hours everyday and charge n810 once per two or free days! And I take notes, checking the mail etc and my tablet keeps the charge for two days minimum.
Ok, tomorrow I will make a test...

default one so 400/133 i guess...
