i got the same thing. removing and installing omap3camd isnt working rebooting isnt also. starting fcam results in having grey screen where the camera view should be.

my thought is that the drivers are damaged...

My camera stopped working after i couldnt shut down my alarm this morning. it crashed and kept playing the anoying sound. then all of a sudden the alarm crashed, accelometer stopped working, camera stopped working and almost everything i launched stopped working.

After reboot all was fixed accept for the camera drivers. MyDocs and sdcard are not read only,
