I'm not sure I follow. How does depmod fail? Unresolved symbols? I
assume 2.4.22-xfs is the name of your kernel, right? If you are not
booted into it then you should specify the kernel symbols to depmod
against using the "-F" option, the file that contains is normally

The low latency patch does not disallow loadable modules. ALSA itself is
loaded as kernel modules and works fine (well, except for bugs of
