A fix for that has been queued, for more info see the thread "v2 2/7] ARM: virt: allow the kernel to be entered in HYP mode". Regards, Tony

That one would break the boot quite early, right? This one has the same symptoms as the serial issue, where it bombs out after: [ 0.948394] Serial: 8250/16550 driver, 4 ports, IRQ sharing enabled [ 0.974273] omap_uart.0: ttyO0 at MMIO 0x4806a000 (irq = 88) is a OMAP UART0 [ 0.986968] omap_uart.1: ttyO1 at MMIO 0x4806c000 (irq = 89) is a OMAP UART1 (hang) - Paul
