A queue in any\nother state (e.g. mid-eviction) keeps its last_fence pending; after a\nGPU reset that fence never signals, so the eviction/suspend worker and\nprocess teardown (amdgpu_evf_mgr_flush_suspend) wait on it forever and\nwedge the machine:\n\n  INFO: task kworker/6:28 blocked for more than 120 seconds.\n  Workqueue: events amdgpu_eviction_fence_suspend_worker [amdgpu]\n  Call Trace:\n   dma_fence_wait_timeout+0x7e/0x130\n   amdgpu_userq_evict+0x67/0x140 [amdgpu]\n   amdgpu_eviction_fence_suspend_worker+0xd8/0x160 [amdgpu]\n   process_scheduled_works+0xa6/0x420\n\nForce-complete every queue's fence regardless of state. The unmap and\nmark-hung step stays gated on MAPPED, since unmapping a queue that is\nnot mapped is invalid.\n\n(cherry picked from commit 9102b39fa924dcc3dc75a3137bfa9633c40b88c0)","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/3085ae8695e025b39d208f288c6265edc75abbe8","https://git.kernel.org/stable/c/5d75ec2e5f1736c2f10c7d6f4565bf1bf29f29a7"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:54.990491175+00:00"},"epss":{"cve":"CVE-2026-68237","score":0.00155,"percentile":0.04653,"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).
