The thread that originates the call is in interrupt\ncontext. The combination of the two trigger a crash. Schedule the call in\nnon-interrupt context where it is more safe.\n\nkernel: BUG: scheduling while atomic: swapper/7/0/0x00010000\nkernel: Call Trace:\nkernel:  <IRQ>\nkernel:  dump_stack+0x66/0x81\nkernel:  __schedule_bug.cold.90+0x5/0x1d\nkernel:  __schedule+0x7af/0x960\nkernel:  schedule+0x28/0x80\nkernel:  schedule_timeout+0x26d/0x3b0\nkernel:  wait_for_completion+0xb4/0x140\nkernel:  ? wake_up_q+0x70/0x70\nkernel:  __wait_rcu_gp+0x12c/0x160\nkernel:  ? sdev_evt_alloc+0xc0/0x180 [scsi_mod]\nkernel:  synchronize_sched+0x6c/0x80\nkernel:  ? call_rcu_bh+0x20/0x20\nkernel:  ? __bpf_trace_rcu_invoke_callback+0x10/0x10\nkernel:  sdev_evt_alloc+0xfd/0x180 [scsi_mod]\nkernel:  starget_for_each_device+0x85/0xb0 [scsi_mod]\nkernel:  ? scsi_init_io+0x360/0x3d0 [scsi_mod]\nkernel:  scsi_init_io+0x388/0x3d0 [scsi_mod]\nkernel:  device_for_each_child+0x54/0x90\nkernel:  fc_remote_port_delete+0x70/0xe0 [scsi_transport_fc]\nkernel:  qla2x00_schedule_rport_del+0x62/0xf0 [qla2xxx]\nkernel:  qla2x00_mark_device_lost+0x9c/0xd0 [qla2xxx]\nkernel:  qla24xx_handle_plogi_done_event+0x55f/0x570 [qla2xxx]\nkernel:  qla2x00_async_login_sp_done+0xd2/0x100 [qla2xxx]\nkernel:  qla24xx_logio_entry+0x13a/0x3c0 [qla2xxx]\nkernel:  qla24xx_process_response_queue+0x306/0x400 [qla2xxx]\nkernel:  qla24xx_msix_rsp_q+0x3f/0xb0 [qla2xxx]\nkernel:  __handle_irq_event_percpu+0x40/0x180\nkernel:  handle_irq_event_percpu+0x30/0x80\nkernel:  handle_irq_event+0x36/0x60","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/78225d6a2a4ffdb2250ce2b7691a9e68a3f86912","https://git.kernel.org/stable/c/78612f2fe8e26637476d756a44f0f05cca0d97de","https://git.kernel.org/stable/c/7fef50214dd04427233a2e66cd624d468e67aecb","https://git.kernel.org/stable/c/826a9d4a00d1424afa961504aec6298ee92d5053","https://git.kernel.org/stable/c/afd438ff874ca40b74321b3fa19bd61adfd7ca0c"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:59:48.811064707+00:00"},"epss":{"cve":"CVE-2022-49156","score":0.00268,"percentile":0.1903,"date":"2026-10-31"},"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).
