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 : https://bbs.archlinux.org/viewtopic.php?pid=2206758#p2206758 Kind regards nbanba -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2047728 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.
