Open Sound System

I have installed the latest Git source using the kernel 3.12 patch. Previously my HDAudio card worked fine, but now the mixer panel is blank and OSS doesn't seem to recognize it fully:

Also, it seems like something is causing IO pagefaults with the Xonar DX:

Also, running osstest causes my computer to become completely unresponsive.

This looks like a very similar issue:

This thread at least provides an explanation:

Why hasn't ASUS fixed the BIOS?

I enabled my IOMMU recently but my ethernet is not having any problems. I'll disable it again and see what happens.

Well, using the iommu=pt kernel option works, so I don't have to disable IOMMU. Finally, I have sound.

Well I just reinstalled my system and had to rediscover this again. This fix was particularly tricky to find. It breaks the HDAudio driver for some people, so really I think it should be added to the driver.

For those wondering how to do it, who are using Grub2, you open /etc/default/grub with root privileges (sudo nano /etc/default/grub) and add iommu=pt to the other options in the default linux command like so:

/etc/default/grub wrote:GRUB_CMDLINE_LINUX_DEFAULT="quiet nomodeset nouveau.modeset=0 iommu=pt"
