Errors while building Kernel for beagleboard

Hi,

Beagleboard version used : B7
Kernel source : page: http://code.google.com/p/beagleboard/wiki/BeagleSourceCode
Linux Kernel : 2.6.22.18

unzipped the tar.gz file
cd to 2.6_kernel directory
make distclean
make omap3_beagle_defconfig
make uImage

uImage built fine without any errors

Next:
cd to 2.6_kernel directory
make distclean
make omap3_beagle_defconfig
make menuconfig
Enable Networking - > Bluetooth subsystem support -> Bluetooth device
drivers -> Enable all
Saved the configuration and exit
make uImage

Build errors resulted:
  LD .tmp_vmlinux1
drivers/built-in.o: In function `fbcon_prepare_logo':
/home/beagle/3Aug2009/2.6_kernel/drivers/video/console/fbcon.c:671:
multiple definition of `context_mem'
arch/arm/mach-omap2/built-in.o:/home/beagle/3Aug2009/2.6_kernel/arch/
arm/mach-omap2/serial.c:297: first defined here
make: *** [.tmp_vmlinux1] Error 1

Unable to resolve this error. If the Bluetooth device drivers are
disabled, then the uImage builds fine.
Please help me in this regard.

Thanks,
Ravi
