Online race starts: black screen

I became host of a game today with megane trophy at spa, was practicing and then I started the race:
black screen and 2-3 times a strange noise came from my speakers. Very weird... I remember this happening (without the noises) in GT5 online, hope they fix it.
I had to close the game going to the ps3 menu, but the ps3 restarted and then asked me to check the filesystem. I was lucky and there were no problems and booted up normally.
