I confirmed that Artful and Bionic already contain commit 903e48531e8b5d414c8f1960eacac24c31f60344, which was included in mainline as of v4.8-rc8.
The commit is not in Xenial, so I built a Xenial test kernel with a cherry pick of it. The test kenrel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1750568/ Can you test this kernel and see if it resolves this bug? ** Changed in: linux (Ubuntu Bionic) Status: Triaged => Fix Committed ** Changed in: linux (Ubuntu Bionic) Assignee: Skipper Bug Screeners (skipper-screen-team) => Joseph Salisbury (jsalisbury) ** Changed in: linux (Ubuntu Artful) Assignee: (unassigned) => Joseph Salisbury (jsalisbury) ** Changed in: linux (Ubuntu Xenial) Assignee: (unassigned) => Joseph Salisbury (jsalisbury) ** Changed in: linux (Ubuntu Artful) Status: Triaged => In Progress ** Changed in: linux (Ubuntu Xenial) Status: Triaged => In Progress ** Changed in: linux (Ubuntu Bionic) Status: Fix Committed => Fix Released ** Changed in: linux (Ubuntu Artful) Status: In Progress => Fix Released -- 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/1750568 Title: qeth: check not more than 16 SBALEs on the completion queue Status in Ubuntu on IBM z Systems: Triaged Status in linux package in Ubuntu: Fix Released Status in linux source package in Xenial: In Progress Status in linux source package in Artful: Fix Released Status in linux source package in Bionic: Fix Released Bug description: Description: qeth: check not more than 16 SBALEs on the completion queue Symptom: Kernel crash Problem: af_iucv socket programs with HiperSockets as transport make use of the qdio completion queue.
