For what it's worth - on a machine with nvme I don't see shutdown_timeout in either
$ ls /sys/module/nvme/parameters/ or $ modinfo nvme
So that's mildly interesting :) Not that it matters here, but I build nvme into my kernels rather than as a dynamic loaded module like arch kernels do.
Interesting on the loaded modules, since there are both nvme and nvme_core, if you do: $ modinfo nvme | grep timeout $ Nothing - but if you do: $ modinfo nvme_core | grep timeout parm: admin_timeout:timeout in seconds for admin commands (uint) parm: io_timeout:timeout in seconds for I/O (uint) parm: shutdown_timeout:timeout in seconds for controller shutdown (byte) parm: apst_primary_timeout_ms:primary APST timeout in ms (ulong) parm: apst_secondary_timeout_ms:secondary APST timeout in ms (ulong) it does have the shutdown timeout parameter. So presumably nvme_core.shutdown_timeout is the right way to set a value, either as command line option (needed when nvme is builtin) or using a file as /etc/modprobe.d/xxx if dynamic loaded. mike -- mike c
