The xmms still keeps hanging in rc11, despite using the "disable suspend" option. I flashed rc11 yesterday and today my Zaurus froze totally while biking to work and listening to music. In addition to the "disable suspend", I had also unwisely selected the "blank screen" option, so when I lost all sound, my Zaurus was both showing blank screen and was totally unresponsive to all keypresses. So I had no practical way to see what was going on or even if my Zaurus was alive or not. Any hints I could do apart from rebooting by removing the battery?

I'm really about this. I really don't care about various kernel tweaks but I'd really like to have applications that actually work in quite typical usage scenarios.

Mine has the same problem but not when its plugged in only on batteries.
I had not gotten to disable suspend yet. Worst case for me is to use my adapter to run the z860 / pdaX on double A batteries. From the Z's perspective it thinks its charging and won't suspend.

I agree it is a frustrating problem. But that is the price for being on the bleeding edge despite the developers shoestring budget.
