Thanks Steve, but I'm still not able to reproduce the kernel crash. If I start netbeans, the current session is killed and I'm thrown back to the login screen. If I do this multiple times the VM eventually simply dies. But no kernel crash. kernel: 4.15.0-49-generic netbeans: 10.0-3~18.04.1ubuntu1 openjdk-11-jre: 11.0.3+7-1ubuntu2~18.04.1 qemu-system-x86_64: /build/qemu-VBsewI/qemu-3.1+dfsg/hw/display/qxl.c:1230: qxl_check_state: Assertion `!spice_display_running || SPICE_RING_IS_EMPTY(>cmd_ring)' failed. 2019-05-14 07:32:36.996+: shutting down, reason=crashed I'm on a Disco host, are you running on Bionic? -- 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/1828632 Title: bionic i386 kernel crashes in memory pressure situations Status in linux package in Ubuntu: Confirmed Status in linux source package in Bionic: New Bug description: The linux-image-4.15.0-49-generic (currently in bionic-proposed) can be made to crash in a kvm guest with memory pressure.

In discussing this with Tyler Hicks, he noted that is a somewhat similar i386 PTI failure report: https://lore.kernel.org/lkml/14206a19d597881b2490eb3fea47ee97be17ca93.ca...@sympatico.ca/ and that the response to it needs fixes from the tip/x86/mm branch. Is it possible that the bionic PTI i386 backports are missing some additional fixes? -- 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/1828632 Title: bionic i386 kernel crashes in memory pressure situations Status in linux package in Ubuntu: Confirmed Bug description: The linux-image-4.15.0-49-generic (currently in bionic-proposed) can be made to crash in a kvm guest with memory pressure.
