Hi

Waiting for a kernel patch (Reproduce in mainline up to Linux 6.10+), I
recommend using the dirty workarround I write to "save" one of my
production server while no patch are currently doing the job and issuing
at kernel cmdline options "nvme_core.default_ps_max_latency_us=0
pcie_aspm=off pcie_port_pm=off" don't have any effect and not more
effect than totally disabling PCIE ASPM in the UEFI BIOS, since Linux
6.1 sysfs is populated with 'd3cold_allowed=1" on NVME and PCIE
downstream port where it should be 0 for NVME storage (Windows seems to
let NVME in D0 state during PCIE ASPM)

More complete explanations and the workaround script can be find here :

Kind regards
