I am using arch/arm/configs/vexpress_defconfig to configure and build Linux Kernel 3.1.1 http://launchpad.net/linux-linaro/3.1/3.1-2011.11/+download/linux-linaro-3.1... and then if I booth the zImage crated on Linaro QEMU http://launchpad.net/qemu-linaro/trunk/2011.10/+download/qemu-linaro-0.15.50... ,it works properly.
But if i enable the LPAE support in the config file, the kernel builds and when I boot the kernel image on QEMU, it just prints the output as :
Uncompressing Linux... done, booting the kernel.
Does your kernel boot OK on real hardware?
(ie, is a kernel with LPAE support expected to boot on a CPU like the A9 which doesn't have LPAE?)
Also if your config/kernel command line don't turn on earlyprintk it's worth enabling this as it usually gets you better diagnostic messages for early kernel boot failures.
