This seems\nto be because of the i40e driver workqueue is allocated with\nthe WQ_MEM_RECLAIM flag, and the i40iw one is not.\n\nSimilar error was encountered on ice too and it was fixed by\nremoving the flag. Do the same for i40e too.\n\n[Feb 9 09:08] ------------[ cut here ]------------\n[  +0.000004] workqueue: WQ_MEM_RECLAIM i40e:i40e_service_task [i40e] is\nflushing !WQ_MEM_RECLAIM infiniband:0x0\n[  +0.000060] WARNING: CPU: 0 PID: 937 at kernel/workqueue.c:2966\ncheck_flush_dependency+0x10b/0x120\n[  +0.000007] Modules linked in: snd_seq_dummy snd_hrtimer snd_seq\nsnd_timer snd_seq_device snd soundcore nls_utf8 cifs cifs_arc4\nnls_ucs2_utils rdma_cm iw_cm ib_cm cifs_md4 dns_resolver netfs qrtr\nrfkill sunrpc vfat fat intel_rapl_msr intel_rapl_common irdma\nintel_uncore_frequency intel_uncore_frequency_common ice ipmi_ssif\nisst_if_common skx_edac nfit libnvdimm x86_pkg_temp_thermal\nintel_powerclamp gnss coretemp ib_uverbs rapl intel_cstate ib_core\niTCO_wdt iTCO_vendor_support acpi_ipmi mei_me ipmi_si intel_uncore\nioatdma i2c_i801 joydev pcspkr mei ipmi_devintf lpc_ich\nintel_pch_thermal i2c_smbus ipmi_msghandler acpi_power_meter acpi_pad\nxfs libcrc32c ast sd_mod drm_shmem_helper t10_pi drm_kms_helper sg ixgbe\ndrm i40e ahci crct10dif_pclmul libahci crc32_pclmul igb crc32c_intel\nlibata ghash_clmulni_intel i2c_algo_bit mdio dca wmi dm_mirror\ndm_region_hash dm_log dm_mod fuse\n[  +0.000050] CPU: 0 PID: 937 Comm: kworker/0:3 Kdump: loaded Not\ntainted 6.8.0-rc2-Feb-net_dev-Qiueue-00279-gbd43c5687e05 #1\n[  +0.000003] Hardware name: Intel Corporation S2600BPB/S2600BPB, BIOS\nSE5C620.86B.02.01.0013.121520200651 12/15/2020\n[  +0.000001] Workqueue: i40e i40e_service_task [i40e]\n[  +0.000024] RIP: 0010:check_flush_dependency+0x10b/0x120\n[  +0.000003] Code: ff 49 8b 54 24 18 48 8d 8b b0 00 00 00 49 89 e8 48\n81 c6 b0 00 00 00 48 c7 c7 b0 97 fa 9f c6 05 8a cc 1f 02 01 e8 35 b3 fd\nff <0f> 0b e9 10 ff ff ff 80 3d 78 cc 1f 02 00 75 94 e9 46 ff ff ff 90\n[  +0.000002] RSP: 0018:ffffbd294976bcf8 EFLAGS: 00010282\n[  +0.000002] RAX: 0000000000000000 RBX: ffff94d4c483c000 RCX:\n0000000000000027\n[  +0.000001] RDX: ffff94d47f620bc8 RSI: 0000000000000001 RDI:\nffff94d47f620bc0\n[  +0.000001] RBP: 0000000000000000 R08: 0000000000000000 R09:\n00000000ffff7fff\n[  +0.000001] R10: ffffbd294976bb98 R11: ffffffffa0be65e8 R12:\nffff94c5451ea180\n[  +0.000001] R13: ffff94c5ab5e8000 R14: ffff94c5c20b6e05 R15:\nffff94c5f1330ab0\n[  +0.000001] FS:  0000000000000000(0000) GS:ffff94d47f600000(0000)\nknlGS:0000000000000000\n[  +0.000002] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[  +0.000001] CR2: 00007f9e6f1fca70 CR3: 0000000038e20004 CR4:\n00000000007706f0\n[  +0.000000] DR0: 0000000000000000 DR1: 0000000000000000 DR2:\n0000000000000000\n[  +0.000001] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7:\n0000000000000400\n[  +0.000001] PKRU: 55555554\n[  +0.000001] Call Trace:\n[  +0.000001]  <TASK>\n[  +0.000002]  ? __warn+0x80/0x130\n[  +0.000003]  ? check_flush_dependency+0x10b/0x120\n[  +0.000002]  ? report_bug+0x195/0x1a0\n[  +0.000005]  ? handle_bug+0x3c/0x70\n[  +0.000003]  ? exc_invalid_op+0x14/0x70\n[  +0.000002]  ? asm_exc_invalid_op+0x16/0x20\n[  +0.000006]  ? check_flush_dependency+0x10b/0x120\n[  +0.000002]  ? check_flush_dependency+0x10b/0x120\n[  +0.000002]  __flush_workqueue+0x126/0x3f0\n[  +0.000015]  ib_cache_cleanup_one+0x1c/0xe0 [ib_core]\n[  +0.000056]  __ib_unregister_device+0x6a/0xb0 [ib_core]\n[  +0.000023]  ib_unregister_device_and_put+0x34/0x50 [ib_core]\n[  +0.000020]  i40iw_close+0x4b/0x90 [irdma]\n[  +0.000022]  i40e_notify_client_of_netdev_close+0x54/0xc0 [i40e]\n[  +0.000035]  i40e_service_task+0x126/0x190 [i40e]\n[  +0.000024]  process_one_work+0x174/0x340\n[  +0.000003]  worker_th\n---truncated---","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/09b54d29f05129b092f7c793a70b689ffb3c7b2c","https://git.kernel.org/stable/c/152ed360cf2d273f88fc99a518b7eb868aae2939","https://git.kernel.org/stable/c/1594dac8b1ed78f9e75c263327e198a2e5e25b0e","https://git.kernel.org/stable/c/2cc7d150550cc981aceedf008f5459193282425c","https://git.kernel.org/stable/c/546d0fe9d76e8229a67369f9cb61e961d99038bd"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:50:30.954589733+00:00"},"epss":{"cve":"CVE-2024-36004","score":0.00246,"percentile":0.15776,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
