I am sorry, but the obove message was just copied from a kernel without the
neomagic driver to show which chip (256AX instead of 256 Zsomething) the
Laptop has. It was not intended to be the message during boot with the new
driver. Given the fact that someone else already gave an exact stack-backtrace
which is identical of what I am getting (ac97_init calls nm_rd with an argument
of 0x600 and size 2 which then does a bus_space_read2 where it hangs. (Names
unfortunately not exact, I do have the code not at my hands))
I have not yet setup a serial console on this machine, so I am not able to
provide you with the boot-messages of the kernel that hangs.
Here is the bootmessage of the kernel without the neomagic-sound-driver
