WD SN750 NVMe resume filesystem goes read only
by IyadKandalaft from LinuxQuestions.org on (#576NT)
I recently replaced my NVMe PCIe Intel 660 with a WD SN750 512GB and simultaneously installed a fresh Ubuntu 20.04.1 LTS as the only OS with UEFI boot. Whenever the system sleeps and then I wake it up, the file system is in read-only mode. If I simply reset the PC, the BIOS can't detect the drive until I power off the PC and turn it back on. So it seems that the drive's controller is in an extended sleep state that it doesn't support and so it can't recover from it; but I'm just speculating.
Obviously, there's no logs for the kernel because it can't write to the drive. I can't determine if this is a BIOS issue, drive issue, or kernel issue.
I'm running kernel 5.4.0-42-generic
Kernel boot options attempted:
pcie_aspm=disabled
acpiphp.disabled=1
nvme_core.default_ps_max_latency_us=10000
Any suggestions as to what I can try? Note that I don't have a Windows license to test the Windows drivers.
