Fresh off the PS3 2.40 firmware "bricking" systems last month, Kotaku is reporting that the new (as of this week) 2.42 firmware is gimping peoples blu-ray drives. WTF?

I updated two days ago, but haven't played any games since. The thread at playstation.com shows case after case of unfortunate souls outraged by their newly malfunctioning PS3's. Has anyone here (with 2.42) had any problems?
