Tony, Thank you for reporting this issue. 1) Can you please provide any information related to the kernel that you are using and conditions prior to this crash? a) what kernel are you running? What has changed in the last week? b) do you have updated Dell System firmware? c) do you have any hardware errors logged? 2) Have you rebooted the system? a) does it cleanly pass selftest? b) does it boot single user mode? c) when you let it boot without interruption, which init stage do you see failure (if repeatable) occur? d) if it passes init stage 4 and is the virtualized environment comes up is it stable?
Please note: It is difficult to successfully determine root cause without logs, dmesg. etc. or knowing the conditions of this system prior to this crash. -- 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/1814628 Title: divide error: 0000 with Ubuntu 18.04 Status in linux package in Ubuntu: Incomplete Bug description: Got a host running lots of virtual machines crashing today with the following terminal output (if that's to any help): [3430458.298979] divide error: 0000 [#1] SMP PTI [3430458.304484] Modules linked in: cpuid vhost_net vhost tap nf_conntrack_ipv6 nf_defrag_ipv6 xt_physdev br_netfilter ip_set nfnetlink kvm_intel kvm irqbypass rpcsec_gss_krb5 auth_rpcgss nfsv4 nfs lockd grace sunrpc cachefiles fscache xt_CHECKSUM iptable_mangle ipt_MASQUERADE nf_nat_masquerade_ipv4 iptable_nat nf_nat_ipv4 nf_nat nf_conntrack_ipv4 nf_defrag_ipv4 xt_conntrack nf_conntrack ipt_REJECT nf_reject_ipv4 xt_tcpudp bridge ebtable_filter ebtables ip6table_filter ip6_tables devlink iptable_filter 8021q garp mrp stp llc bonding ipmi_ssif intel_rapl sb_edac x86_pkg_temp_thermal intel_powerclamp coretemp dcdbas intel_cstate intel_rapl_perf ipmi_si mei_me ipmi_devintf lpc_ich mei shpchp ipmi_msghandler acpi_power_meter mac_hid sch_fq_codel ib_iser rdma_cm iw_cm ib_cm ib_core iscsi_tcp libiscsi_tcp libiscsi [3430458.389747] scsi_transport_iscsi ip_tables x_tables autofs4 btrfs zstd_compress raid10 raid456 async_raid6_recov async_memcpy async_pq async_xor async_tx xor raid6_pq raid1 raid0 multipath linear crct10dif_pclmul mgag200 crc32_pclmul i2c_algo_bit ghash_clmulni_intel ttm pcbc mxm_wmi drm_kms_helper bnx2x aesni_intel syscopyarea sysfillrect aes_x86_64 sysimgblt fb_sys_fops crypto_simd glue_helper ptp cryptd drm pps_core ahci mdio libahci libcrc32c wmi [last unloaded: irqbypass] [3430458.440756] CPU: 1 PID: 0 Comm: swapper/1 Not tainted 4.15.0-43-generic #46-Ubuntu [3430458.450411] Hardware name: Dell Inc.
