Comment 219 for bug 1746340

I've hit this "bug". I've a nice Clevo ODM based laptop and luckily I have two nvme drives in it so it's not a show-stopper for me but obv. it's a concern. I have an Intel one which is the boot drive and a Samsung one which is the data drive. I have a dual-boot setup. So two data points to note. The Intel nvme works in both Windows and Linux. The Samsung works in Windows, but not in Linux. When I say that it doesn't work in Linux I should say that the system brings the drive up, I can mount it read-write, everything looks good but as soon as I try and write files to it it craps out with nothing written:

[369.798910] nvme nvme0: controller is down; will reset: CSTS=0xffffffff, PCI_STATUS=0x10
[369.798916] nvme nvme0: Does your device have a faulty power saving mode enabled?
[369.798918] nvme nvme0: Try "nvme_core.default_ps_max_latency_us=0 pcie_aspm=off" and report a bug
[369.870912] nvme 0000:01:00.0: enabling device (0000 -> 0002)
[369.871064] nvme nvme0: Removing after probe failure status: -19
[369.890931] nvme0n1: detected capacity change from 1953525168 to 0

Output of `dmesg` attached.
