Bug Description
Hi
When running the versatile kernel under qemu with:
qemu-system-arm -m 256 -M versatilepb -cpu cortex-a8 -kernel zImage
I get no video output; I don't know whether the kernel works at all.
Copying the Ubuntu .config in a vanilla 2.6.32 tree and rebuilding gives the same issue, however building with e.g. versatile_defconfig doesn't cause this issue, so it's probably a bug with some configuration item.
Thanks,

I reduced this on top of a vanilla kernel to CONFIG_NO_HZ and CONFIG_ HIGH_RES_ TIMERS. Both are currently set and both need to be unset for the kernel to output anything for me.
