The server has an HPE Smart HBA H240 SATA controller. Since Ubuntu 22.04, the kernel runs into trouble after a few hours of uptime. The problem starts with a few instances of a message such as this: Apr 26 12:03:37 <hostname> kernel: DMAR: ERROR: DMA PTE for vPFN 0x7bf32 already set (to 7bf32003 not 24c563801) Apr 26 12:03:37 <hostname> kernel: ------------[ cut here ]------------ Apr 26 12:03:37 <hostname> kernel: WARNING: CPU: 1 PID: 10171 at drivers/iommu/intel/iommu.c:2391 __domain_mapping.cold+0x94/0xcb Apr 26 12:03:37 <hostname> kernel: Modules linked in: tls rpcsec_gss_krb5 binfmt_misc ip6t_REJECT nf_reject_ipv6 xt_hl ip6_tables ip6t_rt ipt_REJECT nf_reject_ipv4 xt_LOG nf_log_syslog nft_limit xt_limi> Apr 26 12:03:37 <hostname> kernel: drm_kms_helper aesni_intel syscopyarea sysfillrect sysimgblt fb_sys_fops xhci_pci cec crypto_simd i2c_i801 rc_core cryptd drm xhci_pci_renesas ahci i2c_smbus tg3 hpsa> Apr 26 12:03:37 <hostname> kernel: CPU: 1 PID: 10171 Comm: kworker/u4:0 Not tainted 5.15.0-27-generic #28-Ubuntu Apr 26 12:03:37 <hostname> kernel: Hardware name: HP ProLiant DL20 Gen9/ProLiant DL20 Gen9, BIOS U22 04/01/2021 Apr 26 12:03:37 <hostname> kernel: Workqueue: writeback wb_workfn (flush-253:2) Apr 26 12:03:37 <hostname> kernel: RIP: 0010:__domain_mapping.cold+0x94/0xcb Apr 26 12:03:37 <hostname> kernel: Code: 27 9d 4c 89 4d b8 4c 89 45 c0 e8 03 c5 fa ff 8b 05 e7 e6 40 01 4c 8b 45 c0 4c 8b 4d b8 85 c0 74 09 83 e8 01 89 05 d2 e6 40 01 <0f> 0b e9 7e b2 b1 ff 89 ca 48 83 > Apr 26 12:03:37 <hostname> kernel: RSP: 0018:ffffc077826b2fa0 EFLAGS: 00010202 Apr 26 12:03:37 <hostname> kernel: RAX: 0000000000000004 RBX: ffff9f0042062990 RCX: 0000000000000000 Apr 26 12:03:37 <hostname> kernel: RDX: 0000000000000000 RSI: ffff9f02b3d20980 RDI: ffff9f02b3d20980 Apr 26 12:03:37 <hostname> kernel: RBP: ffffc077826b2ff0 R08: 000000024c563801 R09: 000000000024c563 Apr 26 12:03:37 <hostname> kernel: R10: 00000000ffffffff R11: ffffffffc01550e0 R12: 000000000000000f Apr 26 12:03:37 <hostname> kernel: R13: 000000000007bf32 R14: ffff9f00412f5800 R15: ffff9f0042062938 Apr 26 12:03:37 <hostname> kernel: FS: 0000000000000000(0000) GS:ffff9f02b3d00000(0000) knlGS:0000000000000000 Apr 26 12:03:37 <hostname> kernel: CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 Apr 26 12:03:37 <hostname> kernel: CR2: 00001530f676a01c CR3: 000000029c210001 CR4: 00000000002706e0 Apr 26 12:03:37 <hostname> kernel: Call Trace: Apr 26 12:03:37 <hostname> kernel: <TASK> Apr 26 12:03:37 <hostname> kernel: intel_iommu_map_pages+0xdc/0x120 Apr 26 12:03:37 <hostname> kernel: ?

The logged device ID 06:00.0 is the HPE SATA controller. The errors go away after a reboot until the problem occurs again after a few hours. In most cases, the server even reports a hardware fault and the storage fan spins up to 100 %. The problem did _not_ occur in Ubuntu 20.04, the last 20.04 kernel I ran on this server was 5.13.0.39.44~20.04.24. Setting the intel_iommu=off kernel boot parameter seems to work around the problem.
