I hope you can help me without subscribing to the mailing list and remember to include me in the answer discussion.=20 In my old notebook I used an nvme-ssd from WD (wds500g1b0c-00s6u0), which is affected by a well-known bug. I currently use the parameter `nvme_core.default_ps_max_latency_us=3D0` to prevent the system from freezing.=20 I would like to use a new SSD in my new notebook. However, as it is difficult to sell used SSDs, I would like to continue using the old SSD affected by the bug. I plan to move the SSD to a Thunderbolt enclosure for this purpose. I think since Thunderbolt is based on PCIe, the same energy saving measures and the associated bugs will probably apply. In the hope that my new SSD doesn't have the same bug, I would prefer not to disable the Powersafe in the laptop. Is there a way to set this flag only for a specific SSD? By identifying it by name or serial number?=20 I apologise prophylactically if my question is completely out of place and thank you for your help. As a long-time Linux user, I would also like to thank you in general. If you have any follow-up questions, please do not hesitate to contact me. - --=20 Frank Tornack Privat -----BEGIN PGP SIGNATURE----- iHUEARYKAB0WIQSKs5ZJ/d3p8HqrcSZVreqZ0wXqzQUCZbZH7wAKCRBVreqZ0wXq zcQkAPwMA+J3eO/S6T92Gsz9YBamYVHhwLlcUAG3qsYM2g8sRAD/UY+If8RlsT5V uKg89rhH2bnWrVF9PKGU4ZamfHo8eQ0=3D =3Dgfie -----END PGP SIGNATURE-----
