Fwd: Lexar NM790 SSDs are not recognized anymore after 6.1.50 LTS

[Cláudio Sampaio]

Hi Thorsten and Keith,

Thanks for the details. I'm still unsure if responding by email is
better or adding to the ticket, but here it goes: I have tried for
days both with complete power off of the machine and cycle-booting all
kernels in succession and without exception, 6.1.x LTS and the patched
6.5.1 kernel always recognize and operate the NVME, whilst the other
kernels also fail with the same error message. As this is my
"production" desktop, though, during the week it's more difficult to
me to perform tests with it, but I will try to do it in a more
methodic way and also with 6.5.1 vanilla.

As for the reason the Lexar doesn't catch the quirk default, I can't
say I catch the complex logic of the driver activation, but I found
out how to "fix" for my case because there are three other Lexar
models in the pci.c file: NM610, NM620 and NM760 (this one with an
additional quirk marked on it on the code,
NVME_QUIRK_IGNORE_DEV_SUBNQN) -- so I guess whatever justifies the
exception for them also justifies for my model, NM790. Might even be
the case that I would need NVME_QUIRK_IGNORE_DEV_SUBNQN (not sure what
it does) like in the NM760 case, but it activates correctly without
it.
