Summary: alsamixer crashes system when snd-ioctl32 is loaded
Description:
alsamixer crashes system hard when snd-ioctl32 is loaded.
System still responds to some sysrq commands (sync remount boot show) -
sysrq (term killall) has no effect.
There's no chance to do any other keyboard input. No logs, no traps, no
oops. Machine still responds to ping,(even port 22 stays open) but login
via ssh is not possible.
alsamixer, of course, is useless without the ioctl32 wrapper loaded - but
does not crash the system then.
So I suspect a problem in the ioctl32 wrapper.

Hmm, the lockup seems happening because of stack shortage.
Your patch is doing wrong: convert_from/to_32() can't be used for
conversion between kernel and user spaces. They are for between user
spaces.

The attached (hack3) includes fix and more improvements. Doublly
kmalloc()'s are reduced in control and pcm ioctls.
