Hmm, I don't think I have the stock kernel installed anymore. I will try to find out how to revert so I can get you those numbers. I should mention I believe I have one of the worst N900s ever produced - when I first overclocked it a couple of years ago I had to boost the voltages above all of the values in {ideal, lv, ulv, starving} by trial and error to achieve stability, and always without SR. I hoped that I might be able to use SR with frequency range 500-600 just to extend battery life, and then manually OC when I wanted to do something more CPU-intensive.

And the FM transmitter has never worked, no matter which version of fmtxd I tried!

I recently bought a 2nd N900 for a fraction of the price of my older one, and everything (including SR) works very well on it.

Do you use ramzswap by chance?
No, I don't use it anymore - I found it didn't provide any benefit. I reflashed this phone 1 week ago and have been fairly conservative with what I have installed since.

EDIT:

There is really something wrong here, SR VDD2 didn't change through KP versions.
Hmm, okay. In the past I only ever enabled VDD1 (VDD2 was super-unstable on my device), so that may not be relevant.

Hmm, I can't seem to revert to the stock kernel using the instructions here:

I've heard that someone in xda have ported the upstream ondemand governor code from latest linux kernel(and a lot else).
Is that possible for power-kernel? Will that bring us any improvement in daily use?

Given that the N900 already jumps to OPP5 every time you use the device, I don't think much would change.

Ah, freemangordon, I'm running CSSU-thumb, so I guess uninstalling the power kernel to get the info you want from /sys/power/efuse_vddN is not possible.

If I give you a copy of the device file /dev/mtd2 whilst running under power kernel is it any help?

Yeah, flashing stock is not a good idea

Anyway, I still want your efuse values along with your "kernel-config show" output when SR VDD1 is on and tho profile you use to OC and/or undervolt. I want to compare what SR thinks is OK for your device to what is OK in practice. And maybe it is time to do the same for VDD2 SR I did for VDD1 SR. You and your "very bad" device could help a lot for that.

Going back I think I made a general mistake with SR - I preferred slightly better battery life instead of 1-2% worse and a bit higher voltages. But fortunately this is easy to be fixed.

Okay, so with my currently installed KP51 using my own stable undervolting/overclocking profile:

Code:
ash-n900:~# cat /sys/power/efuse_vdd1
0078a384
0089939e
009a82a6
00aaed99
00aada8e
00abb6f2
00aba3db
00ab9ad1
00ab92c6
ash-n900:~# cat /sys/power/efuse_vdd2
0099c485
009a8ec3
00aac695
ash-n900:~# kernel-config show
current kernel configuration:
current frequency: 805
supported frequencies: 125 250 500 550 600 720 805 850 900 950 1000 1100 1150 
min. frequency: 250
max. frequency: 805
avoid frequencies: 125 
active frequencies: 250:38,180 500:34,360 550:38,400 600:42,430 720:50,520 805:54,600 850:60,600 900:60,600 950:60,600 1000:60,600 1100:72,600 1150:72,600 
SmartReflex VDD1=0, VDD2=0
governor ondemand: ignore nice load= 0, up threshold= 95, sampling rate= 300000, powersave bias= 0
And with my modified copy of the 'default' profile with SR VDD1 enabled:

Code:
ash-n900:~# cat /sys/power/sr_vdd1_autocomp 
1
ash-n900:~# cat /sys/power/sr_vdd1_dsp_boost 
125
ash-n900:~# cat /sys/power/sr_vdd1_voltage 
48
ash-n900:~# cat /sys/power/sr_vdd2_voltage 
44
ash-n900:~# cat /sys/power/sr_vdd2_autocomp 
0
ash-n900:~# kernel-config show
current kernel configuration:
current frequency: 500
supported frequencies: 125 250 500 550 600 720 805 850 900 950 1000 1100 1150 
min. frequency: 500
max. frequency: 600
avoid frequencies: 125 250 
active frequencies: 500:48,360 550:54,400 600:60,430 720:60,430 805:60,430 850:60,500 900:60,500 950:60,500 1000:60,500 1100:72,520 1150:72,520 
SmartReflex VDD1=1, VDD2=0
governor ondemand: ignore nice load= 0, up threshold= 95, sampling rate= 300000, powersave bias= 0
What should I do with the device file /dev/mtd2?

as root do "cat /dev/mtd2 > oops.log" without quotes, compress oops.log using whatever you like and upload it here.

Also I want kernel-config show output with SR VDD1 enabled when the device has run for a couple of minutes with it on, so SR had calculated the voltages.

Would be cool if I could use blessn900 again
Thx!
Fcam-drivers from extras-testing (or devel I'm not sure) work with kp and kcssu. They are pretty safe to use, haven't got any issues with them nor I've heard anyone having problems)
