Thanks, applied. Problem did not reappear so far.

Fingers crossed :-).

Ok, I can try. But so far even -rc1 is a lot of fun. But... I consider
phone calls core feature of a phone. I'd very much like to get that to
work. Unfortunately, that means real-time audio, and a lot of
fun. Plus, as it is touchscreen device, it needs a GUI.

Well, I am carrying some patches... but maybe mainline is now good
enough to be useable without them?

No promises. I really should find more time for N900
development. Hmm. Or more developers. Where are all those Eudyptula
Challenge people when you need them?

Best regards,
