Comment 1 Josh Boyer 2014-07-28 00:51:55 UTC

We don't support the proprietary wl driver and you have a workaround.

Comment 2 Alexander Lindqvist 2014-07-28 07:43:10 UTC

Yes this was more like an informational report. Unless there is a problem with the amd_iommu? Report is also sent to Broadcom about this.
