[Bug 2047728] Re: nvme 0000:02:00.0: Unable to change power state from D3cold to D0, device inaccessible

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

Title:
nvme 0000:02:00.0: Unable to change power state from D3cold to D0,
device inaccessible

Status in linux package in Ubuntu:
Confirmed

Bug description:
Ubuntu release: Ubuntu 22.04.3 LTS (ubuntu 23.10 also affected)
Tested on kernal vesions:6.6.8, 6.2.0.39.40~22.04.16_22.04, 6.2.0-39.40~22.04.1, 6.2.0-26.26~22.04.1, 6.0
Hardware: Thunderobot zero, ssd: sumsung990pro, sumsung ssd MZVL2512HCJQ-00B00
bios version: TP117 05/11/2021

BUG discription: ubuntu can't detect one channel of SSD when installing or after installization. This bug is not related to the SSD product itsel but related to the location where it is mounted. Because i have switched these two SSDs, and only the SSD mounted at the same location can be detected. I list the grub log as following:
----------------------------
kernel: ACPI: bus type thunderbolt registered
kernel: thunderbolt 0000:00:0d.2: enabling device (0000 -> 0002)
kernel: nvme nvme1: pci function 0000:03:00.0
kernel: nvme nvme0: pci function 0000:02:00.0
kernel: nvme 0000:02:00.0: Unable to change power state from D3cold to D0, device inaccessible
--------------------------
This error remains when i change kernal versions as list above. This bug is quit similar to bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1942624.
