Hello,
on my new laptop, a HP ProBook 6440b (with Core i5 and a plain Intel Chipset, 4GB RAM) I get randomly freezes of the whole system. I can't reproduce that, what means I don't know a aplication or usage of the system making it freeze. sometimes I have uptimes of a day, without freeze and sometimes it freezes right after booting the system.
I found out, that sometimes the MagicSysRQ (R-E-I-S-U-B) works and let me shut down the system, sometimes not. I don't know what makes that difference. In the system log I can't find any unusual entries. But I foun that the system log is still runing, so shuting down the wifi with the notebooks hardware switch for example is logged. Also the Wifi network connection to my router is not interrupted.

I found this entry in the ubuntuforum, affecting this bug (at least partial other users describe the symptomes I found). But I think it is important to make a difference betweens users system wide freezes and freezes that only affect the mouse and keyboard. ubuntuforums. org/showthread. php?t=1478787
