[PlanetCCRMANews] oracle vbox 3.2.8 and 2.6.31 RT x86_64 = kernel bug

[Luc Tanguay]

Hello,

I'm trying to use VBox 3.2.8 on my PlanetCCRMA'ed Fedora 12 AMD 64-bit 
machine.  VBox (or I should say its kernel module since they are 
generated even when the VM is not running) generates kerneloops, like 
this one (extract from /var/log/messages):

How do I get rid of these messages?

Thanks
