kernel module crash and hangs debian 3.1.8-6134

[Jérémy Lal]

Using this latest debian package, modprobe vboxdrv gives following output.

Please note i'm running debian/sid with kernel 2.6.33-2-686 #1 SMP, and virtualbox debian package version 3.1.6 did not have this problem.

Also i did obviously run /etc/init.d/vboxdrv setup, which compiles the module without errors.

sorry, i should have added this in first place :

• rmmod -f vboxdrv says "module is busy"
• /dev/vboxdrv is not created

[Frank Mehnert]

Please reboot your host and recompile the kernel modules again.

[Jérémy Lal]

i removed vboxdrv init script from init sequence and rebooted.
vboxdrv module (expectedly) is not loaded.
/etc/init.d/vboxdrv setup
recompiles the modules and when done states that /dev/vboxdrv device is not created.
modprobing gives the above log.

[Frank Mehnert]

Please could you double check that the 3.1.6 modules load fine on your box? We cannot reproduce this issue here and AFAICS there were no changes in the host kernel modules between 3.1.6 and 3.1.8
