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.

I tried on top of ubuntu/ubuntu-lucid.git and confirmed that taking the current versatile /boot/config, disabling NO_HW and HIGH_RES_TIMERS, and rebuilding is enough to fix this.
