Since Sony PS3 2.41 Firmware: Call of Duty 4 Crashes

We have all heard about the problems of the Sony PS3 2.40 firmware update and the fact that Sony even pulled this update and went back to just 2.36. Personally I managed to update to 2.40 before they pulled it but as I mostly play Call of Duty 4, I did not see any problems with this firmware release.

Yesterday I updated to firmware 2.41 from 2.40, then after playing Call of Duty 4 for around 10 minutes it crashed when trying to go back to lobby after a game.

This is the first time COD4 has crashed on me and I have clocked up over 150 hours of game time, I thought nothing of it and forced my Playstation 3 to restart by turning the power off.

After another 30 minutes of gameplay, four friends decided to play a private match and on entering that game, COD4 crashed again on me.

Each time the crashes happened the PS3 completely froze, the only way to get access again was to turn the system off and on again.

While I have no way of knowing why these crashes happened, its strange they have happened after updating to firmware 2.41. Has anyone else had any problems with Call of Duty 4 and firmware 2.41 if they updated from 2.40?
