NTFS-3G is userspace driver, not kernel module...

P.S.
the hardware version is 2204.

To be honest, I don't belive in *any* device not being able to handle DSP 600 at all or DSP 600 @ 805 MPU. IT's just a matter of voltage. If disabling vdd1 and using sane voltage result in DSP 600 @ MPU 805 (or even lower, lol) working great, it mean that SR vdd1 calculates too low voltage for such MPU and DSP, yep?

From my subjective perspective, power saving *is* present, with properly functional (= no errors) vdd1 - and I'm think I'm quite prone to placebo effect (I was very skeptical about so-called power saving with SR before freemangordon recalculated them). But, this isn't any dramatic power saving, so I think it's better to take higher voltage reserve, and make it working reliably on majority of devices in any situation, instead of trying to achieve best power-saving.

BTW, isn't there any way of making this value configurable for power-power-powder user, that are sure their devices can take it without errors? Of course I mean SR calculation values. That would allow us to set quite high default ones, still allowing willing people to adjust them.

/Estel

@Estel, I am thinking of a better way to do recalculations of SR calibrations, the way it is done now is not the optimal. Otherwise there should be no problem to export some "SR adjustment" to userspace through sysfs.

And of course for those who has their devices already undervolted to maximum there won't be "magical" battery saving, yet still there are (1-2 hours of heavy usage that is what I see here). And have in mind that biggest consumer is screen, not DSP/MPU, so we are near the maximum possible battery saving that could be achieved

I was reluctant to upgrade from kp48 to kp49 but man, I'm sure glad I did.

I save around 30% battery usage with both vdd 1 and vdd 2 enabled (default profile 250-600) with heavy usage: online mode, watching videos with cutetube, music, email, emulation and mid brightness (3 bars).

My battery was averaging 5 - 6 hours with heavy usage (watching videos non stop) but now my battery averages 8 - 10 hours, again, watching videos non stop.

That's a huge bonus for me, so thanks everyone involved with this kernel, I'm gonna enjoy my n900 for longer now.

Can anybody help me here please

Thanks in Advance

PK49, Feels good man.

Uhm. Just a simple question. I've seen kp49 around for a while, but please don't tell me it uses SR by default? I know that it causes my device to reboot as soon as I enable it.
If it's not enabled, I'll gladly upgrade as there seems to be many useful things here.
Btw, I read there is framebuffer console or something like that..? Would it be possible to boot into a console with that, except for doing those hacks with the bootmenu/multiboot one?

The new kernel-power settings which kp49 needs turns on SR by default.

SR is enabled by default, but don't worry its now very stable on mpu side, your phone will not reboot , you can try playing video content and see the they are stable, if so you can leave it on or disable otherwise.
