The freeze is reproducible and correlates with these kernel messages (from journalctl -b -1 -k at the exact time of the freeze):
May 27 11:19:35 kernel: nvidia 0000:01:00.0: Enabling HDA controller May 27 11:19:35 kernel: NVRM: GPU0 _kgspProcessRpcEvent: Attempted to process RPC event from GPU0: 0x101a (PFM_REQ_HNDLR_STATE_SYNC_CALLBACK) during bootup without API lock May 27 11:19:35 kernel: NVRM: GPU0 nvAssertFailedNoLog: Assertion failed: 0 @ kernel_gsp.c:1447 The same assertion fired 6+ times in the session before the fatal freeze. Triggered by hot-plugging headphones while Slack was initializing audio. ** Description changed: Steps to reproduce: Have an incoming Slack call Plug in wired headphones while Slack is initializing audio System freezes completely, requires hard reboot Kernel messages at time of freeze: - May 27 11:19:35 kernel: nvidia 0000:01:00.0: Enabling HDA controller May 27 11:19:35 kernel: NVRM: GPU0 _kgspProcessRpcEvent: Attempted to process RPC event from GPU0: 0x101a (PFM_REQ_HNDLR_STATE_SYNC_CALLBACK) during bootup without API lock May 27 11:19:35 kernel: NVRM: GPU0 nvAssertFailedNoLog: Assertion failed: 0 @ kernel_gsp.c:1447 May 27 11:19:35 kernel: NVRM: GPU0 _kgspProcessRpcEvent: Attempted to process RPC event from GPU0: 0x101a (PFM_REQ_HNDLR_STATE_SYNC_CALLBACK) during bootup without API lock May 27 11:19:35 kernel: NVRM: GPU0 nvAssertFailedNoLog: Assertion failed: 0 @ kernel_gsp.c:1447 - Environment: Kernel: 7.0.0-15-generic NVIDIA driver: 595.71.05 (Open Kernel Module) Machine: Lenovo (Intel Arrow Lake + NVIDIA dGPU) Ubuntu 26.04 Note: The same assertion appeared 6+ times in the session before the fatal freeze.
