Bug ID: 111711
Summary: IOMMU Xonar Essence STX causes issues
Product: Virtualization
Version: unspecified
Kernel Version: 4.4
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: kvm
Assignee: virtualization_kvm@kernel-bugs.osdl.org
Reporter: bellamorte42@gmail.com
Regression: No
I decided to post this bug here because AFAIK there haven't any real changes to
snd-virtuoso and this bug only occurs with IOMMU enabled. This issue occurs
during normal operation (not running a VM). Attempting to use the xonar
essence results in about 2000 lines of dmesg repeating the following:
[ 38.646702] AMD-Vi: Event logged [IO_PAGE_FAULT device=07:00.0 domain=0x0000
address=0x0000000000100000 flags=0x0050]
[ 38.646707] AMD-Vi: Event logged [IO_PAGE_FAULT device=07:00.0 domain=0x0000
address=0x0000000000100040 flags=0x0050]
[ 38.646709] AMD-Vi: Event logged [IO_PAGE_FAULT device=07:00.0 domain=0x0000

[ 38.646710] AMD-Vi: Event logged [IO_PAGE_FAULT device=07:00.0 domain=0x0000

[ 38.646713] AMD-Vi: Event logged [IO_PAGE_FAULT device=07:00.0 domain=0x0000
address=0x0000000000100040 flags=0x0050]
[ 38.646714] AMD-Vi: Event logged [IO_PAGE_FAULT device=07:00.0 domain=0x0000
address=0x0000000000100000 flags=0x0050]
[ 38.646715] AMD-Vi: Event logged [IO_PAGE_FAULT device=07:00.0 domain=0x0000
address=0x0000000000100040 flags=0x0050]
This also causes any video playback to freeze. I get about 2 frames before
that happens.
This issue was not present under 4.1, 4.2, or 4.3. I think it was 4.4rc3 I
tested when I fist saw it but I did not test the earlier rcs.
