Latest working kernel version: Unknown
Earliest failing kernel version: 2.6.24
Distribution: Gentoo

Hardware Environment:

Echo Indigo-IO audio card
CardBus bridge: Texas Instruments PCIxx12 Cardbus Controller

Problem Description:

I cannot use my Echo IndigoIO PCMCIA card, when I insert the card and my system tries to load the indigoio module I get the following errors (quoted from my kernel log):

### Using the in-kernel 1.0.15 driver (kernel 2.6.24.1, with some debug options turned on):

This bug has already been filed by me in the Alsa bugtracking system, but since it exhibits zero activity I though it will be more appropriate to file it here (ALSA URL: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3743).
