And the problem is that this device fails after some time, though it passes all the health checks and allows itself to be partitioned (unlike NV3)

dmesg: [ 39.925583] nvme nvme0: controller is down; will reset... [ 40.009594] nvme nvme0: Disabling device after reset failure: -19

Adding "nvme_core.default_ps_max_latency_us=0 pcie_aspm=off pcie_port_pm=off" to cmdline didn't help too.

All that was done by testing on latest eeprom with latest rpi-6.12.y linux tree
