Hi,
when starting a video I'm getting the following error with activated IOMMU under Coreboot:
[ 230.800362] AMD-Vi: Event logged [ [ 230.800368] IO_PAGE_FAULT device=08:00.0 domain=0x0000 address=0x0000000073700000 flags=0x0050] [ 230.800371] AMD-Vi: Event logged [ [ 230.800373] IO_PAGE_FAULT device=08:00.0 domain=0x0000 address=0x0000000073700040 flags=0x0050] [ 230.800375] AMD-Vi: Event logged [ [ 230.800376] IO_PAGE_FAULT device=08:00.0 domain=0x0000 address=0x0000000073700000 flags=0x0050] [ 230.800377] AMD-Vi: Event logged [ [ 230.800378] IO_PAGE_FAULT device=08:00.0 domain=0x0000 address=0x0000000073700040 flags=0x0050]
There are over 100 lines in dmesg and it's caused by my Xonar DX sound card. With the proprietary BIOS everthing works fine. I'm using the latest Linux-kernel and the Raptor build config for Coreboot.
This is basically the same bug: https://bugzilla.kernel.org/show_bug.cgi?id=111711
