shawn, as per http://www.gigabyte.com/products/product-page.aspx?pid=3014#bios an update to your computer's buggy and outdated BIOS is available (F7). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, and the information above is provided, then please mark this report Status Confirmed. Thank you for your understanding. ** Tags added: bios-outdated-f7 ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1414334 Title: DMA Errors "DMA: Out of SW-IOMMU space for 2048 bytes at device 0000:06:00.0" Status in linux package in Ubuntu: Incomplete Bug description: Getting Jan 24 09:21:08 tux kernel: [52976.030567] wl 0000:06:00.0: swiotlb buffer is full Jan 24 09:21:08 tux kernel: [52976.030569] DMA: Out of SW-IOMMU space for 2048 bytes at device 0000:06:00.0 In my syslog which eventually ends up breaking all networking on the desktop.
