Its now possible to try my undervolting kernel, which is found from the link in my signature.

EDIT: There is nomore a 125mhz mode in that kernel, as the 250mhz one seemed to run 15minutes 100% stresstest with less voltage than what is defined for the 125mhz mode by stock.

Hi I have a couple of questions:

1. Once you install a kernel..how do you remove it? Just install the default Nokia one with apt-get?
2. If someday PR 1.2 comes out, will it still be able to install with a different kernel?
3. When you say that the lifetime of the device is reduced..does any one know by how much approximately? If it survives two years I would be quite happy. Less..that is an issue.

Does these Lehto's new kernels affect on autoupdating? Do I have to install original kernel back so that I can install PR 1.2?

Please include source patch for every kernel binary you provide.

I just installed your undervolting kernel. It's running nice and stable. Thanks.

One thing, though:
it seems to occasionally switch to 1.1GHz (which I do not want, and which is overvolting according to your download preface). I can pretty much always add 1.1GHz cycles when starting video playback in the media player.

Code:

$ cat /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state 
1100000 2108
800000 51495
500000 36412
375000 1477
250000 146966
$ uptime
01:23:30 up 39 min, load average: 0.00, 0.21, 0.69

Would be nice, if there was a undervolting kernel that does not have the 1.1GHz stage at all.

Yes 250-900 kernel would be sick
