  • We are pleased to report that the UEFI Board of Directors recommends the open source Firmware Test Suite (FWTS) release 15.08.00, see:

    FWTS is a comprehensive tool for ACPI and UEFI firmware testing and has been co-developed by members of the Canonical Kernel Team and Hardware Enablement Team. References:
  • The Kernel Team has released stress-ng 0.05.01 for Ubuntu Xenial 16.04.

    • This tool has been developed to systematically stress test the Linux kernel. Highlights for this release include: a stressor for the new userfaultfd() system call, a new filename stress test and the ability to tweak timer coalescing with the --timer-slack option.
  • Precise, Trusty and Vivid have been updated to be master in Launchpad.

Devel Kernel Announcements

  • Our Xenial master-next branch has been rebased to v4.3 and our first v4.3 based kernel has been uploaded to xenial-proposed in the archive. Please test and let us know your results. Our unstable repo continues to track v4.4-rc3 in parallel. As noted last week, we will eventually rebase both our Xenial master/master-next branches to v4.4 since that is our target kernel version for 16.04.
  • Important upcoming dates:
  • Thurs Dec 31 - Alpha 1 (~ 4weeks away)
