Can I make a request to disable fbcon/framebuffer console on boot? I think it's very unstable and can cause crashes when enabled.
Why do you think that?
It seems to run fine here.
I just rebuild titans meamo40 kernel with te pr1.3 kernel updates. I did not explicitely add the framebuffer console and have not much time right now to lool into it. Thats why I included the patches so other people can jump onto it...

Re: Overclock the N900?
 
Now I'm running mirakels kernel-power v41. Stable so far but one problem:

I cannot record a video, the camera app is closing when I try to record a video. Same problem as with Titans power-kernel v40.

Video recording on Titans kernel-power v37 is working.

My N900 is running at 500-900 Mhz. I did some heavy duty tests at 900 Mhz - the N900 is stable at 100% CPU load on 900 Mhz for several minutes.

What if you stop all overclocking but keep Titan's kernel? Can you record a video?

Uhm well I read that a looong time ago :p
Here's a quote from titan himself

That's why I have disabled it.
If you nonetheless want to test it you can install the older version maemo8 from http://repository.maemo.org/extras-d...free/k/kernel/

Now I tried different frequencies:

Video recording is only possible with 600 - 800 Mhz. Anything higher will crash the camera app. :(
But with Titans kernel-power v37 I was able record videos with 900 Mhz.

I'm just uploading version power41 to extras-devel.
(sorry for the delay, I've have been sick, and been distracted from maemo)

Wow! Welcome back titan and thanks! ^_^

@titan any chances of including compat-wireless in a next build?

Hope your feeling better :D

MohammadAg added USB hostmode to your kernel. Anything about that in v41?

Have you tried upping the volts? That have been the reason before when people have had problem with video recording. The DSP and CPU uses the same volt... too low and it will not have enough power for DPS thus video stops working.
