Would the kernel normally use a serial console when booting in an Integrity VM, or does it go through an virtualized framebuffer? I've never tried it, but Documentation/kernel-parameters.txt has this: earlycon= [KNL] Output early console device and options. uart[8250],io,<addr>[,options] uart[8250],mmio,<addr>[,options] uart[8250],mmio32,<addr>[,options] Start an early, polled-mode console on the 8250/16550 UART at the specified I/O port or MMIO address. MMIO inter-register address stride is either 8-bit (mmio) or 32-bit (mmio32). The options are the same as for ttyS, above. My zx6000 shows the following serial ports on boot, so it's possible setting earlycon= to one of these might give more information (you'll want to cross check where the VM maps these ports): Serial: 8250/16550 driver, 4 ports, IRQ sharing enabled 00:04: ttyS0 at MMIO 0xff5e0000 (irq = 49) is a 16550A 00:05: ttyS1 at MMIO 0xff5e2000 (irq = 50) is a 16550A > If you find out anything more, I'm most interested. I'll try. Unfortunately I don't have much room for experimenting with the machine since it is running some production services and I also only have physical access to it during working hours. (I bought an MP board for it, but could never get the console working on it.) If you can easily try different kernels on your VM, maybe it would be worth trying the normal -itanium kernel and possibly the kernels from unstable. In any case, thank you for confirming that the problem exists; I'll go file a bug in the BTS. Regards, Martin
