This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:
apport-collect 1850284 and then change the status of the bug to 'Confirmed'. If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'. This change has been made by an automated script, maintained by the Ubuntu Kernel Team. ** Changed in: linux (Ubuntu) Status: New => Incomplete ** Tags added: disco -- 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/1850284 Title: Failure when creating multiple VMs with sr-iov port Status in linux package in Ubuntu: Incomplete Bug description: When creating a multiple in the row KVM instances with an SR-IOV interface this way: manually - openstack port create --vnic-type direct --network sriov-net sriov-portN (2 sec pause) - openstack server create --port sriov-portN --image bionic-sriov --availability-zone nova:hostname --flavor m1.small --key-name maaskey test-sriovN (2 sec pause) and x 5 times. The host hangs, stops being accessible via juju ssh, ssh attempt to bondm address gets connection refused. Icmp to host gets response though. If I type password manually in ilo console - there is no bash prompt after it. After rebooting I found the following in journalctl : Oct 29 08:26:23 hostname kernel: general protection fault: 0000 [#1] SMP PTI Oct 29 08:26:23 hostname kernel: CPU: 8 PID: 7405 Comm: libvirtd Not tainted 5.0.0-32-generic #34~18.04.2-Ubuntu Oct 29 08:26:23 hostname kernel: Hardware name: HPE ProLiant DL380 Gen10/ProLiant DL380 Gen10, BIOS U30 05/21/2019 Oct 29 08:26:23 hostname kernel: RIP: 0010:i40e_sync_vsi_filters+0xaa/0xca0 [i40e] Oct 29 08:26:23 hostname kernel: Code: 00 00 00 48 89 85 78 ff ff ff 48 8b 83 10 02 00 00 48 c1 e8 03 48 89 85 70 ff ff ff 83 e0 01 88 45 8b 48 8b 03 48 85 c0 74 17 <8b> 80 38 02 00 00 8b b3 0c 02 00 00 31 c6 89 83 0c 02 00 00 89 75 Oct 29 08:26:23 hostname kernel: RSP: 0018:ffffb91a77ac7708 EFLAGS: 00010286 Oct 29 08:26:23 hostname kernel: RAX: 8287194a20ac1de7 RBX: ffff9c5594638000 RCX: 0000000000000000 Oct 29 08:26:23 hostname kernel: RDX: 0000000000000001 RSI: 00000000fffffe01 RDI: ffff9c5594638000 Oct 29 08:26:23 hostname kernel: RBP: ffffb91a77ac77b0 R08: 0000000000000000 R09: 00000000000024f8 Oct 29 08:26:23 hostname kernel: R10: 00000000000024f8 R11: 0000000000003e25 R12: ffff9c57670e2580 Oct 29 08:26:23 hostname kernel: R13: ffff9c5594638000 R14: ffff9c5763896000 R15: ffff9c5594638a28 Oct 29 08:26:23 hostname kernel: FS: 00007f386be92700(0000) GS:ffff9c077f800000(0000) knlGS:0000000000000000 Oct 29 08:26:23 hostname kernel: CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 Oct 29 08:26:23 hostname kernel: CR2: 00007f3851d53e17 CR3: 0000004d76f4e003 CR4: 00000000007626e0 Oct 29 08:26:23 hostname kernel: DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 Oct 29 08:26:23 hostname kernel: DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Oct 29 08:26:23 hostname kernel: PKRU: 55555554 Oct 29 08:26:23 hostname kernel: Call Trace: Oct 29 08:26:23 hostname kernel: ?
