Package: linux-image Version: 6.11.10-amd64 On a Dell Precision 3650 Tower (Firmware Version: 1.35.0),we have two Samsung SSD 990 PRO with Heatsink 4TB with different firmware versions shutting down randomly with the following message:
```Dec 30 08:05:11 [redacted] kernel: nvme nvme1: Disabling device after reset failure: -19 Dec 30 08:05:11 [redacted] kernel: nvme 0000:02:00.0: Unable to change power state from D3cold to D0, device inaccessible Dec 30 08:05:11 [redacted] kernel: nvme nvme1: Try "nvme_core.default_ps_max_latency_us=0 pcie_aspm=off pcie_port_pm=off" and report a bug Dec 30 08:05:11 [redacted] kernel: nvme nvme1: Does your device have a faulty power saving mode enabled? Dec 30 08:05:11 [redacted] kernel: nvme nvme1: controller is down; will reset: CSTS=0xffffffff, PCI_STATUS=0xffff
```Device is thereafter not responsive to any command using the `nvme` command. Starting the system with the suggested kernel parameters yields no change (the previous log snippet is taken from a system started with those arguments).
