Yesterday my phone was working perfectly without swap for whole day. Unfortunatelly in the evening something happened, phone suddenly restarted and didn't boot. It hangs on Cyanogen(mod) logo. I tried to wipe all data and install ROM again, it worked, but after second restart it stopped to boot again. I don't know what to do with it.
EDIT: After wiping data system starts again, so maybe there is some problem in /data or /cache partition?
