[vbox-dev] vboxdrv setup fails

Dear List,
I am on FC11, kernel-
This kernel was built from source in order to enable the rt2860sta driver,
which is by default disabled on the stock ditribution kernel.
kerne-devel-  is installed as well as
I had installed installed VirtualBox-3.0.2_49928_fedora11-1.i586
PRIOR to recompiling the kernel from source in order to enable rt2860sta driver.

If I type service vboxdrv setup, the compilation proceeds without any problems.

Now if i type service vbosdrv start, I get:
# service vboxdrv start  
Starting VirtualBox kernel module                          [FAILED]
  (modprobe vboxdrv failed. Please use 'dmesg' to find out why)

dmesg does not reveal any messages regarding the starting or loading of the vboxdrv driver.

If I do

modproble -f vboxdrv

I get:

 modprobe -f vboxdrv   
FATAL: Error inserting vboxdrv (/lib/modules/ Invalid module format

So, I do not understand what the problem with the format is. All I can
extract from the module is:

# file /lib/modules/>
/lib/modules/ ELF 32-bit LSB relocatable, Intel 80386, version 1 (SYSV), not stripped

This is the same info I get about the loaded drivers as well, i.e.:
ELF 32-bit LSB relocatable, Intel 80386, version 1 (SYSV), not stripped

So, what is this invalid format problem caused by?

# uname -r

uname -a
Linux localhost.localdomain #2 PREEMPT Sat Aug 1 23:17:53 PDT 2009 i686 athlon i386 GNU/Linux

The PREEMPT is displayed because I chose a preemptible kernel option which helps improve interactive response time. The difference between
preemptible kernel and non-preemptible kernel as far as response time is concerned, is noticeable on my uniprocessor laptop.

Thank you for your help.
If you need any further info, please let me know.

Best regards,


Get back to school stuff for them and cashback for you.
