I am running kernels 2.4.16 with low latency patches and the RTC patch 
from alsa-package-rc3
and 2.4.18 without any patches alternatively. The alsa-package was rc-3 
and is now the current
CVS-version. In all cases envy24control and amixer contents lead to the 
system lock (amixer without contents works fine!)

I have started "strace envy24control" which let me know that

ioctl(4, 0xc245512, 0xbfffedb0)

is the instruction that causes the system lock. Multiple ioctls with 
only the third argument differing
returned 0 just before the system lock.

When calling amixer contents, the last message printed is:

numid=103, iface=mixer, name='Input Sensitivity Switch', index=1
    ; TYPE=enumerated, access=rw---, values=1, items=2
    ; Item #0 ='+4dBu'
    ; Item #1 = '-10dBV'


In comparison to the previous outputs coming from amixer contents
the following line is missing:
    ; values=0

Any idea?

Regards,
Hauke
