[LAD] 2.6.31.x vs. rme vs. alsa 1.0.22?

Hey, has anyone been seeing strange behavior from this combination? kernel 2.6.31.x rt20 + alsa 1.0.22 userland RME card (pcmcia card + multiface) hdspmixer is not doing the right thing (does not initialize the card in a way in which playback works), it does not see the hwdep interface (or something like that) and disables metering, alsamixer even segfaults when I reach the end of the controls listed. Plain weird. Smells like something changed deep in the kernel that makes alsa-lib very unhappy. Alsa-tools rebuilt from source does not make a difference. Weirdness goes away when I boot into 2.6.29.6 rt23... Is there anything in alsa-* that depends on which _kernel_ is available at compile time? -- Fernando
