Could you try the latest upstream kernel which convert dm-crypt's
tasklet to BH workqueue? I suppose the commit fb6ad4aec1d0 ("dm-crypt:
Convert from tasklet to BH workqueue") might resolve the issue.And mantic master-next has disabled tasklets for dm-crypt. https://git.launchpad.net/~ubuntu- kernel/ubuntu/+source/linux/+git/mantic/commit/?h=master- next&id=13104eddc76990dc3e4183cff050c9b6dc5e859e I suppose hwe-6.5 will sync from mantic later, so please try with the newer kernel. BTW, could you share how to reproduce the issue? I can try from my side in case above commits doesn't help. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe-6.5 in Ubuntu. https://bugs.launchpad.net/bugs/2051232 Title: kernel: BUG: Bad page state in process kworker Status in linux-hwe-6.5 package in Ubuntu: Confirmed Bug description: Similar to the bug https://bugs.launchpad.net/ubuntu/+source/linux- hwe-6.5/+bug/2051123 where traces were shown, we observed a "BUG" being reported on yet another machine of the same make / model (Asus RS720A-E11-RS24U using dual socket AMD EPYC Milan CPUs): ``` [...] Jan 24 08:57:00 fra-az1-comp-24 kernel: BUG: Bad page state in process kworker/u257:18 pfn:5812dc Jan 24 08:57:00 fra-az1-comp-24 kernel: page:00000000b0c63dd1 refcount:-1 mapcount:0 mapping:0000000000000000 index:0x0 pfn:0x5812dc Jan 24 08:57:00 fra-az1-comp-24 kernel: flags: 0x17ffffc0000000(node=0|zone=2|lastcpupid=0x1fffff) Jan 24 08:57:00 fra-az1-comp-24 kernel: page_type: 0xffffffff() Jan 24 08:57:00 fra-az1-comp-24 kernel: raw: 0017ffffc0000000 dead000000000100 dead000000000122 0000000000000000 Jan 24 08:57:00 fra-az1-comp-24 kernel: raw: 0000000000000000 0000000000000000 ffffffffffffffff 0000000000000000 Jan 24 08:57:00 fra-az1-comp-24 kernel: page dumped because: nonzero _refcount Jan 24 08:57:00 fra-az1-comp-24 kernel: Modules linked in: vxlan ip6_udp_tunnel udp_tunnel ebt_arp nft_meta_bridge xt_CT xt_mac xt_state xt_comment xt_physdev vhost_net vhost vhost_iotlb tap xt_CHECKSUM xt_MASQUERADE xt_conntrack ipt_REJECT nf_reject_ipv4 xt_tcpudp nft_compat nft_chain_nat nf_nat nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 nf_tables nfnetlink xfrm_user xfrm_algo nvme_fabrics 8021q garp mrp br_netfilter bridge stp llc bonding binfmt_misc tls nls_ascii ipmi_ssif intel_rapl_msr intel_rapl_ common amd64_edac edac_mce_amd kvm_amd kvm irqbypass rapl wmi_bmof irdma ib_uverbs ib_core joydev input_leds ccp k10temp ptdma switchtec acpi_ipmi ipmi_si ipmi_devintf ipmi_msghandler mac_hid sch_fq_codel efi_pstore ip_tables x_tables autofs4 dm_crypt raid10 raid456 async_raid6_recov async_memcpy async_pq async_xor async_tx xor raid6_pq libcrc32c raid0 multipath linear hid_generic usbhid hid cdc_ether usbnet mii ast i2c_algo_bit drm_shmem_helper raid1 drm_kms_helper ice crct10dif_pclmul crc32_pclmul po lyval_clmulni polyval_generic Jan 24 08:57:00 fra-az1-comp-24 kernel: ghash_clmulni_intel aesni_intel crypto_simd cryptd ahci nvme gnss drm i40e libahci xhci_pci i2c_piix4 xhci_pci_renesas nvme_core nvme_common wmi Jan 24 08:57:00 fra-az1-comp-24 kernel: CPU: 14 PID: 1094271 Comm: kworker/u257:18 Not tainted 6.5.0-14-generic #14~22.04.1-Ubuntu Jan 24 08:57:00 fra-az1-comp-24 kernel: Hardware name: To be filled by O.E.M.
