    Subject[sparc] Weird ioctl() bug in 2.2.19 (fwd)
    Right now I'm looking into why SNDCTL_DSP_SETFMT is failing on 2.2.19
    sparc. I've been trying to get ESD to work on my SS20 box so I can play
    music.

    The situation is that the ioctl() is failing with -EINVAL for a perfectly
    valid argument.

    Here's the strace output from running ESD (snipped for brevity)

    open("/dev/dsp", O_WRONLY) = 3
    ioctl(3, 0x6004500a, 0xefffe944) = 0
    write(1, "DEBUG: 60045005\n", 16DEBUG: 60045005) = 16
    write(1, "DEBUG: 00000010\n", 16DEBUG: 00000010) = 16
    ioctl(3, 0x60045005, 0xefffe944) = -1 EINVAL (Invalid argument)

    The debug statements I put in ESD shows the right argument with the right
    value is being passed by the ioctl() call. 0x00000010 is AFTM_S16_BE, by
    the way.

    I've had a look at audio.c in /drivers/sbus/audio (lines 1046 to 1144),
    and everything looks correct, down to the parameters, so why is it
    returning -EINVAL?

    Weird. Any ideas?
