NVMe suspend failure

[Bart Van Assche]

Hi,

Even after having added nvme_core.default_ps_max_latency_us=0
pcie_aspm=off to the kernel command line, the following still
appears in dmesg -w output upon suspend of an x86_64 workstation:

[ 2451.640676] nvme nvme0: controller is down; will reset: 
CSTS=0xffffffff, PCI_STATUS=0x10
[ 2451.640690] nvme nvme0: Does your device have a faulty power saving 
mode enabled?
[ 2451.640694] nvme nvme0: Try "nvme_core.default_ps_max_latency_us=0 
pcie_aspm=off" and report a bug

Hence this email. From the nvme id-ctrl output:

mn        : Samsung SSD 970 EVO Plus 500GB
fr        : 2B2QEXM7

Please let me know if you need more information.

Thanks,

Bart.
