Hello
I got a kernel null pointer dereference while i load the vboxdrv kernel module. I have a custom build kernel: Linux joshua 2.6.19.1 and a debian 'testing' system
In kern.log I found this:
Mar 7 21:02:19 joshua kernel: vboxdrv: Trying to deactivate NMI watchdog permanently... Mar 7 21:02:19 joshua kernel: vboxdrv: Successfully done.
