Problem with multiple hvc consoles via virtio-console

Hello,

When multiple hvc console ports are initialised and used via the
virtio_console driver, I can interact with only the first console, the
2nd one doesn't respond.

If I call hvc_kick() even if hvc_poll() returns 0, the 2nd console
becomes responsive.

I've checked that hvc_poll() receives data via get_chars() and feeds it
to tty_insert_flip_char().

Any idea what could be going wrong? This is reproducible on Linus' git
kernel as the guest kernel with the qemu.git repo.

Any pointers?

Thanks,
		Amit
