    As Sebastian Ssmoller pointed out in [1], the pcm(4) driver doesn't work
    on an ASUS M2400N notebook with a RELENG_5_2 system. I'm having the same
    problem now, on the same model:

    | pcm0: <Intel ICH4 (82801DB)> port 0xe100-0xe13f,0xe000-0xe0ff at device 31.5 on pci0
    | pcm0: unable to map IO port space
    | device_probe_and_attach: pcm0 attach returned 6

    What wasn't said in that thread was that this did work in 5.1 (with ACPI
    enabled), as you can see from the dmesg output available at [2]. The
    complete dmesg output of the current system is attached to this mail. (I
    don't know if it's of any relevance, but it might be worth mentioning
    that IRQ 5 occurs frequently in it.)

    Maybe this helps to find the cause of the problem.
