Machine 1: intel-em-kmod-7.7.5, nvidia-driver-390.87_3, virtualbox-ose-kmod-5.2.32_1 . Machine 2: drm-fbsd12.0-kmod-4.16.g20190722_1, gpu-firmware-kmod-g20190= 620, virtualbox-ose-kmod-5.2.32_1 - uname -a: FreeBSD hal.xyzzy 12.0-RELEASE-p9 FreeBSD 12.0-RELEASE-p9 #9 r350677M: Wed Aug 7 18:35:55 CEST 2019=20=20=20=20 root@v908.xyzzy:/.../hal/z/OBJ/FreeBSD/amd64/releng/12.0/amd64.amd64/sys/XY= ZZY_SMP amd64 Result: - On two of the three machines I have now experienced something which seems like a livelock: Some processes are stuck, others still progress and can be terminated (e.g., EOF in shells). - Rebooting the machines never succeeds completely: At some point there is = no progress anymore and the machines have to be hard reset. - In the first livelock, two tabs of Firefox seemed to be "stuck" against e= ach other; 100% CPU was used (1 out of 4 cores). - In the second livelock, VirtualBox (VBoxHeadless) was spinning at 100% (1= out of 4 cores), and a running svn command was stuck. I have the impression that this started with -p9. Before, I mostly got pani= cs with immediate reboots (no kernel dumps although configured; see bug report #235865). -- Martin --=20 You are receiving this mail because: You are the assignee for the bug.=
