qemu: hardware error: integratorcm_read: Unimplemented offset


I am trying to build kernel, filesystem image and simulate generic arm board on qemu.

I have cross-compiling toolchain created with Crosstool-ng:
./ct*ng arm*-unknown-*linux-*uclibcgnueabi

I've created initramfs root file system and successfully tested it with downloaded pre-build kernel image zImage.integrator:
qemu-system-arm -kernel zImage.integrator -initrd initramfs.cpio.gz

Now I am trying to build latest kernel ( for arm:

make ARCH=arm defconfig
make ARCH=arm menuconfig

In menuconfig I've added the following options:
General Setup --->
Initial RAM filesystem and RAM disk (initramfs/initrd) support
Configure standart kernel features (for small systems)

Kernel features --->
Use the ARM EABI to compile the kernel (allowing also old ABI)

Then I compiled:
make ARCH=arm CROSS_COMPILE=arm-linux-

When I run it with qemu I got the following error:

dave@dave-desktop:~/Embedded/sysdev/arm-test$ qemu-system-arm -kernel zImage -initrd initramfs.cpio.gz

qemu: hardware error: integratorcm_read: Unimplemented offset 0x1f1018

CPU #0:
R00=00013ebf R01=00000000 R02=00000055 R03=00000113
R04=101f1000 R05=0000000d R06=001869bb R07=001869fc
R08=00000000 R09=001869f8 R10=001869f4 R11=001869e4
R12=101f1000 R13=001879e0 R14=00010a64 R15=00010858
PSR=200001d3 --C- A svc32

Could anyone advise or give me a hint how to troubleshoot this problem.
