That can cause the flag to be\n      stale over a shutdown/startup sequence\n\n    - When a non-forced event is armed, which then prevents rearming before\n      that event. If that event is far out in the future this will cause\n      missed timer interrupts.\n\n    - In the suspend wakeup handler.\n\nThat led to stalls which have been reported by several people.\n\nAdd the missing resets, which fixes the problems for the reporters.\n\n## Affected\n\n- `Linux >= d6e152d905bdb1f32f9d99775e2f453350399a6a < 9401b593fa48218d2667df1610b0ebc518554880`\n- `Linux >= d6e152d905bdb1f32f9d99775e2f453350399a6a < 4096fd0e8eaea13ebe5206700b33f49635ae18e5`\n- `Linux 7.0`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
