Guess WiFi leads to system hang when swap is on.I failed to crash the system without the swap, I tried hard. But, of course, there another problem pops up - application processes (acore, phone) crash when the memory runs out.
Forgot to say, I finnaly switched to the newest build. It's hard to say, what helped me to do that - a more stable release (I took msmission's core), or because I installed a new Radio ROM, or something else.Prior that, when I tried a new (after 09-06-09) core (the kernel and the root.img) the phone freezes when I tried to call on it. Now it's not.
So sad to say, turning WiFi off still hangs the phone even when the swapping was turned off.
I made a knight's move, took the latest build and changed it.Instead of using swap on the SD card now it uses ramzswap virtual device as it was in old more stable releases.We'll see...
