Can't compile/unload vbox modules on linux host (kernel: 3.0.0.7)

[Alexander Bierbaumer]

Hi there!

Tried to compile modules with kernels: 3.0.0.7 and 2.6.39

Modules are loaded as permanent (didn't even know this is possible) and vboxdrv can't unload it

dmesg:

    BUG: unable to handle kernel paging request at 23599500
    IP: [<f8845101>] VBoxPciLinuxInit+0x101/0x1000 [vboxpci]

and

    Pid: 14641, comm: modprobe Not tainted 3.0.0-7-generic #9-Ubuntu Dell Inc. Latitude E6500                  /0W612R

lsmod:

    vboxpci                32018  1 [permanent]
    vboxnetadp             13328  0 [permanent]
    vboxnetflt             27252  0 [permanent]
    vboxdrv               251877  3 vboxpci,vboxnetadp,vboxnetflt,[permanent]

during vbox install:

modprobe vboxpci failed. Please use 'dmesg' to find out why

vboxdrv setup:

    * Stopping VirtualBox kernel modules                                                                                                                                           
    * Cannot unload module vboxpci

As it seems, that there is a bug in DKMS I uninstalled DKMS, purged Virtualbox and tried to reinstall:

Install:

    addgroup: The group `vboxusers' already exists as a system group. Exiting.
