[Kernel-packages] [Bug 1842850] Re: NULL pointer dereference in kvm_mmu_flush_or_zap
We had the issue 2 times within ~3 weeks, so we moved the system out of production, updated every firmware possible, started loadtesting - but are unable to enforce it. We now moved the system back to production so see if the issue happens again (~2 weeks ago). I will report as soon as we have the issue again. -- 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/1842850 Title: NULL pointer dereference in kvm_mmu_flush_or_zap Status in linux package in Ubuntu: Expired Bug description: tonight one of our systems run into the following panic -- kernel NULL pointer dereference at kernel: [2468259.002689] IP: kvm_mmu_flush_or_zap+0x5/0x40 [kvm] kernel: [2468259.007758] PGD 0 P4D 0 kernel: [2468259.010483] Oops: [#1] SMP PTI kernel: [2468259.014161] Modules linked in: vhost_net vhost tap xt_nat xt_REDIRECT nf_nat_redirect ip6table_mangle xt_mark xt_connmark xt_multiport xt_set ip_set_hash_net ip_set xt_CT xt_mac veth vxlan ip6_udp_tunnel udp_tunnel ip6table_raw xt_physdev xt_comment xt_CHECKSUM xt_tcpudp iptable_mangle iptable_raw ebtable_filter ebtables nf_conntrack_netlink nfnetlink xfrm_user xfrm_algo br_netfilter bridge aufs rbd libceph binfmt_misc 8021q garp mrp stp llc bonding openvswitch nsh nf_conntrack_ipv6 nf_nat_ipv6 rdma_ucm(OE) ib_ucm(OE) nf_defrag_ipv6 ib_ipoib(OE) ip6table_filter ib_umad(OE) xt_conntrack mlx5_fpga_tools(OE) mlx5_ib(OE) ib_uverbs(OE) iptable_filter mlx4_ib(OE) mlx4_en(OE) mlx4_core(OE) ipt_MASQUERADE nf_nat_masquerade_ipv4 xt_addrtype iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 nf_nat nf_conntrack kernel: [2468259.085884] ip_tables ipmi_ssif intel_rapl skx_edac x86_pkg_temp_thermal intel_powerclamp coretemp kvm_intel kvm irqbypass crct10dif_pclmul crc32_pclmul ghash_clmulni_intel pcbc aesni_intel aes_x86_64 crypto_simd glue_helper dell_smbios dcdbas cryptd intel_cstate dell_wmi_descriptor wmi_bmof intel_rapl_perf mei_me mei lpc_ich shpchp ipmi_si ipmi_devintf ipmi_msghandler acpi_power_meter mac_hid rdma_cm(OE) iw_cm(OE) ib_cm(OE) ib_core(OE) iscsi_tcp libiscsi_tcp libiscsi scsi_transport_iscsi ip6_tables x_tables autofs4 mgag200 i2c_algo_bit ttm mlx5_core(OE) mlxfw(OE) devlink drm_kms_helper syscopyarea sysfillrect bnx2x mlx_compat(OE) sysimgblt ptp fb_sys_fops pps_core mdio drm libcrc32c ahci libahci wmi kernel: [2468259.148257] CPU: 21 PID: 3455197 Comm: CPU 11/KVM Tainted: G OE4.15.0-55-generic #60~16.04.2-Ubuntu kernel: [2468259.158712] Hardware name: Dell Inc.
