Haven't yet noticed anything else wrong in the system.
Using kernel-power 250 - 900 Mhz, ulv

Any ideas why and what is wrong?

Still continuing. I rebooted, but it didn't fix the problem.
About 15 / min of those messages in syslog (dmesg, /var/log/syslog)

I saw a lot of these errors before I realised they were caused by undervolting too much.
A reboot (as opposed to a full shutdown) seemed to cause it to happen much more frequently.

Yes, undervolting seems to trigger it.
DSP is not getting enough power, I guess.

Normal reboot won't fix it, nor loading the normal non-overclocked non-undervolted settings after reboot. Maybe removing the battery would work.

For example, with settings below it still does it, if it has started to do it in the first place.
I think these should be "normal" non-undervolted + non-overclocked settings:
Code:
# kernel-config show
current kernel configuration:
current frequency: 250
supported frequencies: 125 250 500 550 600 700 750 805 850 900 950 1000 1100 1150 
min. frequency: 125
max. frequency: 600
avoid frequencies: 125 
active frequencies: 0:30,90 250:38,180 500:48,360 550:54,400 600:60,430 700:60,430 750:60,430 805:60,430 850:60,500 900:60,500 950:60,500 1000:60,500 1100:72,520 1150:72,520

governor ondemand: ignore nice load= 0, up threshold= 95, sampling rate= 300000, powersave bias= 0
modprobe -r dspbridge
modprobe dspbridge
Loading dspbridge driver back to the kernel will make the system crash:

Got rid of it by overclocking to 900 and enabling SmartReflex, after N900 crashed, rebooted, and the problem was away.

I can find couple of crash logs of dspbridge from my system, if someone is interested to debug.
