VirtualBox 1.5.6 with Linux Kernel 2.6.25

While compiling VirtualBox was successful, the loading failed with kernel message (seen using dmesg | tail -f):

release/bin/src ; USER=root ; COMMAND=/sbin/modprobe vboxdrv
Apr 23 22:20:16 linux-hp kernel: vboxdrv: Unknown symbol change_page_attr


With the introduction of the new API, no driver nor non-archcore code needs to use change_page_attr anymore. What I did was to grep for "change_page_attr" in VirtualBox source directory:

grep -R --include=*.? "change_page_attr"

And comment out all calls to this procedure. Loading the module then succeeded:

release/bin/src ; USER=root ; COMMAND=/sbin/modprobe vboxdrv
