open("/dev/mixer", O_RDWR) = 4
ioctl(0x4, 0x40044dfe, 0x2563c) = -1 (errno 22)
No dice, matches up just fine. Any more ideas?
Could be a compiler bug then, put some debugging printk's into
sys32_ioctl(), one right before the big switch which goes:
printk("sys32_ioctl(before switch): cmd(%08x) "
"SOUND_MIXER_READ_DEVMASK(%08x)\n",
cmd, SOUND_MIXER_READ_DEVMASK);
Then put a similar printk right below the case for
SOUND_MIXER_READ_DEVMASK itself.
This bug would explain some problems I had with the gnome mixer applet
and some other sound programs on sparc64...
