We see timeouts from the device. hdaudio: RIRB timeout hdaudio_mixer_attach: Codec #0 is not responding hdaudio: Codec attach failed (-5) oss: Probing the hardware for Intel High Definition Audio (Azalia) controller failed. The same driver code seems to work perfectly in Linux, Solaris and OpenBSD that we also have installed on the same machine. We've tried to see if it's a OSS thing or FreeBSD thing but the code looks a-ok because it works in OpenBSD/Solaris/Linux, so I'm not sure what might the problem be. I suspect it may be how FreeBSD handles PCI-Express bus. If someone from the kernel group is interested in helping us solve this problem, I'll be happy to work with them fix the problem.
