Either the memory ranges are broken, or the IRQ. Do you know, by chance,
which does cause this failure? You could test whether it is the memory range
by adding reserved=0xff490000,0x00aff000 to the kenrel boot line, and check
whether it works.

On very most systems there is no such crash; in fact, your notebook seems to
be the first on where the autoconfiguration fails.

Could you send me a complete dmesg, please?
