NVME WD SN520 not found

[Deblau73]

Hello,
On a HP 705-G4-Sff with SSD, it’s impossible to capture or deploy an image.
The version of the fog server is 1.5.5 and the last kernel 4.19.6.
The bios is in Legacy with no secure boot.
In debug mode, i have hd=/dev/nvme01.


Thanks in advance for your help.

Hello,

My problem is solved by a modification of the bios.
I unchecked the PCI Express Power Management box and the Extended Idle Power States box.

Thanks.

This is a real interesting error. Its not clear if its a hardware controller error, disk error, or a linux kernel issue.

Do you have a second computer of the same model you can test on? Do you get the same results?

I don’t have a second computer right now but i plugged the SSD (SN520) into a computer Dell and it’s OK.
I plugged the SSD of the Dell (Toshiba) on the HP-705-G4 and it’s OK.
On the 705-G4 with the SSD SN520, it’s OK with a boot winpe.

Thanks
