Multiple users report the PCMCIA Audigy 2 adapter hangs the machine in 2.6.21 while it work OK in 2.6.20:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=242208

Which version of ALSA is this using? cat /proc/asound/version Has it correctly identified the sound card? cat /proc/asound/cards I don't think that anything has changed in the driver between 2.6.20 and 2.6.21 that would affect this. That PCMCIA card can rather easily hang the machine due to it's design, but removing the PCMCIA card during the hang should release the hang state and the PC should continue. There was one case where it would continue to hang, but I believe I fixed that. Please tell me the output of the above two cat commands, and I will then have a better idea of what the problem is. Kind Regards James

In the hope that it helps, the initialization of the Audigy 2 ZS Notebook still succeeds on my laptop, but it does seem noisier then usual lately (this writing to ADC failed message): Advanced Linux Sound Architecture Driver Version 1.0.14 (Thu May 31 09:03:25 2007 UTC).

Also, I would like to say that although this card works on an x86 laptop, it has severe difficulties in a PowerBook. In that machine it can not be hotplugged, and needs to be inserted before powerup, and removal with the power on results in a kernel oops.
