Thank you, i found this command in the other thread and executed yesturday :
midclt call system.advanced.update '{"kernel_extra_options": "nvme_core.default_ps_max_latency_us=0 pcie_aspm=off pcie_port_pm=off"}'
It did not crash yet, i will put it under load, and see how it goes today.
Note :
Looks stable from yesturday evening to today 10:29 - i mark this as solution, and will unmark it if i have a crash later.
BUT : this command line is a temporary fix, it will probably crash after next Truenas update, so i will have to relaunch command after each Truenas update until fixed in truenas/linux.
So this probably should be ascalated to Truenas team to be fixed, i don’t know how to do this.
